With iBeacon, Apple is going to dump on NFC and embrace the internet of things

At WWDC in June, Apple (s aapl) quietly announced iBeacon, one of the more prominent features of iOS 7. Craig Federighi, Apple’s senior vice president of Software Engineering, mentioned nothing about about it in the keynote, and Apple hasn’t provided any details about it; it was only seen on one slide in the WWDC keynote.

iBeacon Apple WWDC 2013 iOS 7

Nor did Apple say anything about it during the iPhone event Tuesday. But I’m sure this is going to be a big deal, and startup companies like Estimote agree, announcing its support for Apple’s technology Tuesday and releasing this demonstration video.

Why is that so? For a couple of reasons: it opens a door to new set of applications such as indoor maps and in-store marketing, it makes the internet of things a realty and it might kill NFC (near-field communications), the wireless technology most linked with mobile payments.

What is iBeacon?

Using Bluetooth Low Energy(BLE), iBeacon opens up a new whole dimension by creating a beacon around regions so your app can be alerted when users enter them. Beacons are a small wireless sensors placed inside any physical space that transmit data to your iPhone using Bluetooth Low Energy (also known as Bluetooth 4.0 and Bluetooth Smart).

For example, imagine you walk into a mall with an iPhone 5s (comes with iOS 7 and iBeacon). You are approaching a Macy’s store, which means your iPhone is entering into Macy’s iBeacon region. Essentially iBeacon can transmit customized coupons or even walking directions to the aisle where a particular item is located. It can prompt a customer with special promotions or a personalized messages and recommendations based on their current location or past history with the company. Smartphones that are in an iBeacon zone will benefit from personalized microlocation-based notification and actions.

In the age of context, iBeacon can provide the information you needed when it is needed. Just like NFC, iBeacons even allow you to pay the bill using your smart phone. The best part? iBeacon can run for up to two years on a single coin battery and it comes with accelerometer, flash memory, a powerful ARM processor and Bluetooth connectivity. Also, you can add more sensors to iBeacon to provide better context.

What is BLE?

As the name implies, Bluetooth Low Energy (BLE) is built specifically to consume small amounts of energy and make phone batteries last longer. But there are limitations with BLE when it comes to transferring data. BLE only supports very low data rates and you cannot stream audio using BLE. You can send small files using BLE and it is a good candidate for small data packets sent from wearable computing such as smart watches and fitness trackers. Built-in platform support for BLE was only added in Android 4.3 (some Android OEMs like Samsung and HTC did develop their own SDKs for BLE prior to Google releasing native support), which is why fitness tracker apps won’t work on some old Android phones.

Why it might be a NFC killer?

iBeacon could be a NFC killer because of its range. NFC tags are pretty cheap compared to NFC chips, but NFC tags are required on each product because NFC works only in very close proximity. In theory, NFC range is up to 20cm (7.87 inches), but the actual optimal range is less than 4cm (1.57 inches). Also, mobile devices need to contain a NFC chip that can handle any NFC communications. On the other hand, iBeacons are a little expensive compared to NFC chips, but iBeacons range is up to 50 meters. Not all phones have NFC chips, but almost all have Bluetooth capability.

Why it is so affordable?

Let’s go back to Macy’s. The average area occupied by a Macy’s store is 175,000 square feet, which is 16,258 square meters. iBeacon’s range is 50 meters (typical Bluetooth range), or 2,500 square meters. So a typical Macy’s store would need 7 iBeacons.

Estimote, a company which just launched to sell beacons, is taking pre-orders at the price of $99 for 3 beacons. The range of Estimote’s beacons is 50 meters, but the recommended range is 10 meters. If you go with the recommendation, you need 1 Estimote beacon for every 100 square meters, which would cost you about $5,000. If Macy’s wanted to add NFC tags (each at 10 cents) to all its products to send information to phones, it would cost $1,000 for 10,000 products, $10,000 for 100,000 products and $100,000 for 1 million products. NFC may not be needed on all products, but this will give a rough idea on how much it could cost.

Google’s focus is on NFC; it just added BLE support to Android

Google has been heavily focused on NFC from the beginning and it didn’t add platform support for BLE until the release of version 4.3. Lot of the apps that rely on BLE couldn’t release the apps for Android phones. Some Android OEM vendors recognized the need and rolled out their own implementations. Google finally listened to the demand and made it part of Android 4.3. But Google has continued to push on NFC and rolled out the NFC-based Android Beam in Android 4.0.

Apple’s focus on Bluetooth

iPhone5c20131-3

Apple has avoided NFC, and all the rumors about NFC getting added to iPhone 4 and iPhone 5 are turned out to be false. Instead of NFC, Apple worked on alternatives using Wi-Fi and Bluetooth. During the introduction of iOS 7’s AirDrop at WWDC in June, Apple’s mobile development chief Craig Federighi said, “There’s no need to wander around the room, bumping your phone,” referring how NFC phones need to be very close to transfer the data. As stated on Apple’s website:

AirDrop lets you quickly and easily share photos, videos, contacts — and anything else from any app with a Share button. Just tap Share, then select the person you want to share with. AirDrop does the rest using Wi-Fi and Bluetooth. No setup required. And transfers are encrypted, so what you share is highly secure.

New set of applications

With built-in microlocation geofencing features, iBeacon opens a door to new set of applications in indoor mapping. The GPS signals inside malls are very poor as the signals travel by line of sight, meaning they will pass through clouds, glass and plastic but will not go through most solid objects such as buildings and mountains.

This is the biggest problem for indoor navigation. Google has done in-store maps, but it couldn’t implement indoor navigation because of the line of sight issue. This is where iBeacon’s micro-location feature is going to shine.

From your smart phone, you’ll be able to connect to a nearest iBeacon and get its hard coded GPS location to navigate or use the signal to move to closer to iBeacon. iBeacon supports “enter” and “exit” events, so it can send different notifications while entering into the range and exiting out of the range. Imagine having a museum indoor tour with navigation, in-store navigation to the physical products, or navigation to terminals inside airports and subways.

BLE is the answer to internet of things

To make the internet of things a reality, a sensor’s form factor is very crucial. Size, affordability and internet connectivity are the key factors in a sensor. The possibilities are endless if you could control all sensors these remotely; switching on the AC on the way back home, controlling the refrigerator temperature based on the weather, controlling the room lighting from your smart phone, and so on. Estimote is also working on reducing the size of its beacons so that that they will be more affordable.

Apple has found a smart way to wirelessly transmit data over short distances using BLE. So why do you need to bump your phone with another? Why do you need NFC if you could share the data with anyone in the region with the existing bluetooth technology?

BLE can solve these microlocation data challenges in ways that NFC can’t duplicate.

    How do you connect your phone to an iBeacon? Do you have to connect to each iBeacon in the store or are they all on the same “network”? What about when I go to another store do I then have to connect to those iBeacons?

  4. The big semiconductor guys build combo chips that have Bluetooth, WiFi and NFC. So NFC can be added at low cost. Apple just hasn’t figured out a compelling user experience and business model around it.

    • Julio Laker

      Agreed, and when their patents for gifting iTunes vouchers via NFC are approved they’ll simply update the OS to enable the capability that’s already in the chip. No new hardware required.

  5. Idon't Know

    NFC is pretty much already dead and Google Wallet along with it. I work in the payments architecture industry and NFC is dead in the water because vendors don’t want to implement it. Bluetooth LE is likely the future because vendors can count on all phones having it and that makes it worth the investment.
    Google Wallet is probably not long for this world. It costs Google more than they make from it. Nobody wants to use it because they don’t trust Google and there is no critical mass for NFC making it worth the expense of readers. it would be dead already if it wasn’t so high profile for google but i think it will be gone soon.
    Of course if you have an Android phone feel free to rant about how great NFC and Google wallet even though you know nothing about the subject of payments.
    Oh and no NFC tags don’t work for payments..seriously I have to explain this?…it takes far more infrastructure than that.

    As always: certain technologies are better matches to certain use cases than others; clever names and hype help to launch new tech; and some people like to get excited about new ideas at the expense of existing and perfectly viable solutions. NFC – excellent for smart labelling and artefact driven transactions (I’m not going to put iBeacons on 1000 bottles of fine wine); BLE great for micro location applications. NFC is cheap (I’m puzzled at how anyone can truly compare 30c versus $30 cost and maintain that cost is a barrier for NFC!) and durable and highly suited to open Web services. Of course the latter are anathema to Apple, so the fact that you’ll have to develop an app to deploy your iBeacon service suits Apple down to the ground! On the other hand, tapping is not appropriate in some use cases and iBeacons will hugely win out there. We’re supporting both techs even though – for the reason given above – I don’t expect Apple to go NFC any time soon. But the fact that it doesn’t support it doesn’t make the real world requirements go away… So hopefully Google and others will continue to support it.

  8. Typical tech blog confusing Apples and Oranges.

    NFC is being deployed world-wide as a mobile payment standard. Even in the U.S., ISIS is rolling out nationwide; and all payment terminals are required to include NFC by 2015 (for Visa and Mastercard). iBeacon doesn’t achieve diddly squat when it comes to mobile payments.

    So, if you’re in Europe or China and want to hop on public transportation, you’re out of luck.

    Apple’s market share will decline, particularly overseas, due to the simple omission of NFC.

    Why are Apple not including NFC is the real question?

    The answer?

    Greed.

    They don’t want to allow 3rd party payments to flow through their devices where they can’t skim off transaction fees.

    It is short sighted, foolish and does consumers no good at all. They have a plastic case, drop in NFC and authenticate with finger print sensor. Then, let mobile payments thrive.

  9. Hernando Zambrano

    Every time Apple Introduce a new technology , they always make it easy for developer and users to use and I thinks this is the best advantage over other platforms.

    AirPlay – AirPrint – AirDrop ….

    • TheRealCBONE

      “AirPlay – AirPrint – AirDrop ….” The ease of use comes from keeping it Apple only rather than sticking to the standard and having to figure out compatibility with everything possible. The list of bluetooth smart and wifi direct devices is helluva long.

  10. “Just tap Share, then select the person you want to share with. AirDrop does the rest using Wi-Fi and Bluetooth.”

    Why hit a button then scroll a long list of people to select one when you can just bumb your phone and let NFC, bluetooth and wifi do the work?

    “you need 1 Estimote beacon for every 100 square meters”

    How many differents articles in 100 square meters in Macy’s? How do I select the one I need? Isn’t a nfc tag by in front or near article simpler to select one?

  11. Jon Hendry

    I took the “no bumping” comment at WWDC as a specific reference to the app Bump, which doesn’t use NFC to transfer data: the data actually transfers via Bump’s servers. The Bump app on the two devices detects the physical contact, and uses that information to arrange the transfer via the servers.

  12. Brian T Edwards

    Don’t forget, NFC does not need to be “synced” with the source to receive a transmission like BLE. NFC is always on and can actually send data based on contextual triggers, rather than BLE which need to receiver to proactively (as opposed to passively) express an interest in receiving said data by literally flipping a switch. Also, as some others have commented, NFC works without any power at all.

  13. Jody Fanning

    IBeacons and NFC solve two totally different problems which undermines the whole argument.

    For starters the iBeacon concept you describe is old. I have received Bluetooth advertisements walking past a shop in a mall probably 8 years ago in Finland. It is just a slightly updated version of the same concept Nokia was pushing a decade ago.

    The other mistake is that NFC is two different concepts, one case is between two active devices, and that is usually just a method to initiate a separate secure channel via wifi or Bluetooth. So the close contact _is_ the user acceptance for connection. In an iBeacon case there would have to be a separate pairing action required from the users.

    The other part is the passive RFID. Your iBeacons concept doesn’t handle that case at all. With passive RFID I can tag every shelf in a store independently and it requires no batteries at all. The tags could lead directly to my app or to a web page for the product. How can 3 iBeacons in a store solve that case?

  14. We at lumedo.com compared different technology stacks (WiFi, Bluetooth,…) before eventually using BLE. Still, prices of the chips are to high for ubiquitous computing systems. But we appreciate apples move into the BLE direction, which will enable even more hardware driven development. Hopefully they stick to that plan and that Google will integrate BLE in their devices (efficiently!).

  15. Dominik Sommer

    IMHO the technologies are complementary, not competitive: beacons solve the “What’s around” class of questions, while NFC is more suitable for specific (trans)actions.

    Consider some scenarios:
    – Museum tour: I want my phone to “know” where I am -> beacon
    – Subway: I want to explicitly tell the operator I want to ride, without any app interaction -> NFC
    – Mall: I want that coupon by just entering the store -> beacon
    – Share image/links/… while talking to a friend: I don’t want to browse a list of Bluetooth devices, just touch our two phones -> NFC

    – Dominik

  16. Adam Simon

    The high-level here is all generally correct, but there are some serious misunderstandings of what ibeacon is and what it’s capable of. Without breaking the (still-valid) NDA: it’s a new Bluetooth profile that allows ranging based on general proximity to a Bluetooth device.

    The idea that a !acu’s would “need” 7 ibecons is absurd without a valid use case. A Macy’s may need one (to trigger upon entry), twenty (one for each register); or 500 (one for each rack), depending upon the desired experience.

    The author is right that this is an under-appreciated development in iOS 7, and will be important going forward. He just has no clue how it actually works.

      • wjackson2112

        You realize that there’s no Apple hardware to learn the “internals” of right? iBeacon as defined by Apple isn’t a device, it’s a protocol that is sent over BLE. Companies like Estimote and Roximity are just building devices that mimic what can already be done on iOS7 equipped devices. iBeacon is just a bunch of numbers sent over BLE. If you have the right equipment and stare at them long enough, it’s not hard to figure out what Apple is doing to make this witchcraft work.

          • I can see the opportunities of an iOS7 device beaconing its presence and identity to fixed infrastructure. But imagine using this for payment. It won’t work when your iOS7 device has run out of battery. I would not want to go shopping and worry about whether or not my phone is still up & running so i can pay….

            I rather use my (NFC/chip&pin) bank card, which is not battery dependent. It always works and is NOT constantly connected to the internet of things. Yes, also an NFC smart card can be hacked. It all depends on the type of NFC chip and its security level and you’d have to be close. There are also solutions coming to the market that will prevent scavenging NFC whilst in your wallet…

      • wjackson2112

        It’s just a formatted stream of numbers on a BLE advertisement. Way simpler than it seems. You just break it down into little pieces to get the data you need to work with iBeacon. They’re piggy backing on BLE to create this new functionality. Basically, BLE and iBeacon aren’t two names for the same thing, but iBeacon wouldn’t exist w/o BLE.

  17. It’s important to understand that square footage of the store is irrelevant to iBeacons.

    All you need is ibeacons at all possible entrances and exits, and “maybe” (but not even required) at escalators and elevators. iBeacon features will be about geofencing, not continuous coverage.

    You might also have iBeacons at the entry points to major departments, llike Mens, Shoes, whatever. You might even have beacons at specific displays. This will all depend on the merchandising strategy and whether brands (like Sephora) want special coverage.

    The placement of the beacons is really crucial. But you are fencing, not covering square footage.

    • Hari Gottipati

      Agreed, the ideal case could be just placing iBeacons at entrances and exits, but I am giving an example where a store wants to provide custom coverage based on the aisle/category/product.

      • Hari Gottipati

        Yes, that’s what I meant by custom coverage based on the aisle/category/product. If you want the custom coverage such as walking directions, you need to place them every where in the store.

        • Jim Bonner

          Yes that’s one use case but even in that case, square footage isn’t the driver. At that point, the number of aisles/displays/departments is the driver. It’s highly unlikely that your navigation app will even want (much less need) continuous coverage).

          The key with iBeacons is to shake yourself free of the GPS paradigm. You really don’t want or need GPS coordinates in most cases.

          But, admittedly, that is my opinion!

      • Steven Ickman

        Do you really need an iBeacon to give you directions within a store? Every major store I’ve ever been to has giant signs all over the place telling you what department you’re in. That’s assuming you can’t just look at the stuff around you and tell. Same goes with Malls. While you could use your phone to get directions they have this thing called a “Directory” that works pretty well.

        If anything you want an iBeacon to do one of two things in stores: 1) pay for stuff. which means you need an iBeacon compatible payment system at the register. 2) give you more info about a specific product like reviews, price comparisons, etc.

        For the first one both iBeacon and NFC are pretty much on a equivalent so pick one.

        For the second iBeacon has an issue. There are thousands of products in a store. You’re probably not going to give every product its own iBeacon so at best you’ll have one beacon per department. That means you need UI for finding the product your trying to get more info about. That also means users will have to search for the product in that UI that they’re looking at. Compare that to the NFC experience. You’re standing in front of a product and you tap an NFC tag for that product…. Which seems faster?

        On top of the obvious issues of scale, as others have mentioned iBeacons require power and NFC tags don’t. I can buy a blank NFC tag on amazon for about $1 which means a large retailer could probably get them for around $0.20 each. That’s about the cost of the battery needed for an iBeacon costs and it never has to be replaced…. Which seems more cost effective?

        • pkdecville

          “Do you really need an iBeacon to give you directions within a store?”

          Huh?

          One of my most annoying waste of times is to walk into a store new to me with a list of find and buy items with the need to find the signs (Which category might be the one I’m looking for?) or be totally puzzled needing to find a free clerk.

          Best examples – Small Items at Walmart, Lowes, HomeDepot, Large Groceries.

          With iBeacon, I have a list of items with aisles, maps, shelving level, and car map type directions leading me directly to what I’m buying with no wasted steep or minutes.

          Most people I know would kill for this.

  18. Stupid Apple tryng to call bluetooth tech another name just so they can own it. Would you want your phone to be a bait by broadcasting its presence saying “here i am ready to be hacked”!? As opposed to NFC being close range where you ensure you only transact/pay what you touch/hover it on. And fyi, nfc is just a coilf wires and a chip connected to a battery. Thats why soke samsung phoje has it optional because some are just sandwiched on the battery themselves. No need to have it inside the phone circuitry. Easy.

    • “Stupid Apple tryng to call bluetooth tech another name just so they can own it.”
      Which tech are they trying to call their own?

      Let’s do a search on any of the many Internet search sites to see how easy it is to hijack an NFC transaction. Do some research, before posting opinions based on assumptions of technologies that you know nothing about. Easy. You’re an ignorant fool.

      • jasonlhendry

        FUD – all the articles I found on this topic talk about browser exploits iniiated by an NFC phone to phone bump. If you don’t secure your protocols you will get scammed, just like you don’t leave open ports listening or bluetooth on all the time. It’s sad that users have to be knowledgable about their security to the degree that they must understand the ramifications of their actions, but then again, burying your head in the sand doesn’t work in the real world either. Sooner or later you’re gonna lose some money to fix it or make it go away.

    • wjackson2112

      iBeacon is just a particularly formatted BLE advertisement. There’s no reason that an Android device, or any BLE equipped device for that matter, could take advantage of a beacon. iOS7 is just equipped to handle and work with the beacon at an OS level. An Android app could use a beacon as well, but it would be the responsibility of the developer to translate what the iBeacon packet means. On iOS7, it’s like 3 lines of code and then the OS monitors it in the background. Apple has done nothing but provide a format and documentation for a technology that already exists. They haven’t tried to own it or say that anyone else can’t use it.

    • Dan Knight

      Likewise “The range of Estimote’s beacons is 50 meters, but the recommended range is 10 meters. If you go with the recommendation, you need 1 Estimote beacon for every 100 square meters…” should be 314 square meters.

  19. Guna Sekaran

    I tend to agree with all but one on iBeacon bill payments. When Visa and Mastercard are lobbying for NFC and making payment terminals, how will iBeacon fit into the scheme of things between customers and banks – is a big question.

    I somehow believe that the bill payments via NFC would be more apt and close to conventional card payments. And above all we need to be bothered about card security while paying at few feet distance.

    • “Visa and Mastercard are lobbying for NFC and making payment terminals”
      That’s because they have already invested in the technology. Th problem is, the merchants are being charged for the units, and for the transactions. Most retailers want nothing to do with NFC.

      And NFC being “more apt and close to conventional card payments” is just ignorance. NFC is just a method of transmission and has nothing to do with how secure the actual transaction is. Do a Google search to see how easy it is to hijack an NFC transaction.

      • Fraser Harris

        The merchants are being charged for the hire of an eftpos terminal and the transactions that they process through that terminal. The actual method of payment is irrelevant (i.e. Magnetic Strip Swipe, Contactless (NFC) or Chip Insert.

    • It will be so interesting to see how iBeacon is going to break the barrier in terms of payment. Bank has its own security system, and when it goes down to the technology routine, they act more conservative and defensive than anyone else. Why do they need to rewrite the whole system to catch a case which only happens when people forgot their wallet?

      The real solution is to minimise the loose, the maximum you can spend per transition with NFC contactless payment is just enough for a sandwich + bottle of coke. It is akin to an emergent payment than anything else. At the end of day, you still need your wallet and bank card if you expect a decent shopping.

      Payment is the last thing to consider in terms of the use of whatever iBeam or NFC. Micro-location exploration sounds more promising to improve a shopping experience.

  20. Why it might be a NFC killer

    No. it won’t. NFC tags do not require power and can be printed into wall poster. Besides this, NFC is more suitable for secure communications because of a very low proximity. and as you said , Google has already added BLE support to Android 4.3 => Apple has no advantage here as well.

    • Hari Gottipati

      Google added BLE support in Android based on the demand and it is still focusing on NFC. It’s just matter of a focus for Google to go after indoor navigation apps with BLE. Agreed, NFC do not require power, but NFC chips are expensive. Cost is the huge factor here and I am sure, in future we see all smart phones (even low cost smart phones) having Bluetooth, but not necessarly a NFC chip.

    • There are, what, like dozens of Android devices in the world with BLE and Android 4.3? I’m not taking about different models, but total devices in people’s hands. While there are over 100 million iOS devices with BLE. NFC has been a pretty big bust. (I’ve never met a human who has used NFC for anything, ever.) So these iBeacons, with a monstrous number of devices already ready for it, have a decent chance of becoming popular. And if these iBeacons do become popular, the vast majority of Android users won’t be able to take advantage unless they buy a new phone in 2014 or later. It’s sort of like how Android got Vine _eventually_, but not until they were frustrated for months watching all their iPhone-toting friends using it. iPhone users may push stores to use BLE beacons, and if they do, it will mostly be iPhone users taking advantage of the beacons, not Android users.

      • TheRealCBONE

        The HTC One, and the galaxy s3 and s4 all already support wifi direct and BLE. That’s dozens of millions in hands. No bumping needed. 4.3 isn’t needed, either. Google was late to the dance on that one.

      • TheRealCBONE

        There are a zillion android phones that support wifi direct and BLE. The HTC One, galaxy s3 and s4. That’s several dozens of millions right there. Android 4.3 isn’t needed and neither is NFC, so no bumping needed either. Seems their big problem is not giving things another fancy name like netburst, ibeacon, or blast processing and sticking to the lame industry designations.

      • Ron Miller

        > I’ve never met a human who has used NFC for anything, ever

        I’ve spent time in Japan, and they use NFC a lot. For example, the entire train system uses NFC for ticketing. You charge money on your “Suica card”, and then you swipe it when you enter a station. When you exit, it figures out the correct fare and deducts it form your account. It is an incredibly convenient system!!!

        I wonder if BLE could do the same thing. With the trains and turnstiles, the proximity is important, and it needs to be a near instantaneous transaction.

        Can BLE tell distance and could it be set up to only interact with phones that are within 10cm or so?

        • Hernando Zambrano

          “I wonder if BLE could do the same thing. With the trains and turnstiles, the proximity is important, and it needs to be a near instantaneous transaction.

          Yes it can …

          • wjackson2112

            Not to mention you also have to ability to extend that functional range to say 2m (not really possible w/ NFC) and then just be able to step on the bus or through the turnstile and never have to take your phone out of your pocket at all. You also still have the flexibility to use the 10cm distance if it’s a security concern.

            • Ross Whiteford

              Side effects may include irradiation of your balls, but still… ;-)

              (Seriously though, I know there was some noise about the dangers of Bluetooth radiation a few years ago. Is BLE considered less of a risk?)

          • Kevin Ferguson

            Yes, it can, but it’s not exactly accurate! BLE uses RSSI-based localisation techniques such as triangulation and fingerprinting. None of these methods are perfect. RSSI is affected by many factors like obstacles, multipath fading, antenna polarisation and cross-body shielding.

            Personally, I wouldn’t trust BLE at any range with any faith in its accuracy, as factors beyond your control could easily skew the results. Also, have you seen the Estimote beacons? They would make easy targets for removal, thus rendering iBeacon useless.

            iBeacon will end up only being installed in Starbucks and The Gap, where most Apple users hang out…

      • US-centric fan boys need to open their eyes. NFC is used by millions of people everyday for mobile payments and access to public transit. The iBeacon is cute but you can also do it with an Android phone, the devices are already on the market.

        Android 4.4 (KitKat) will support BLE and older devices (I’m guessing as far back as Android 2.3). That’s a pretty huge proportion of the billion android devices currently in the wild.

        Actually, I use NFC a lot. There’s a chip embedded in a few of my credit/debit cards. Once Google wallet integration is available in Canada, I’ll save a step by just bumping my phone against the terminal instead of reaching for my wallet.

        Perhaps a few Fixed wheel bicycle & Fedora shops will be early adopters for the iDevices, but I suspect it’ll be Android users that determine whether BLE or NFC wins.

        Probably because you only hang out with other pretentious iSnobs like yourself. Tough to get any diversity when all your opinions are the same.

      • NFC on a phone or NFC in general? There are quite a few NFC users in Los Angeles because the “TAP cards” are NFC. TAP cards are required to use the Metro rail service. Around the world NFC cards are using for ticketing. It is a very popular technology. The DoD is working to upgrade their CAC system to use NFC. Full end-to-end PKI. Any phone that uses a hardware crypto chip + NFC would work as a virtual CAC.

    • “Low proximity” has nothing to do with security. That same feature has been used to describe as a security feature for a whole host of technologies including WiFI, BlueTooth, and RFID. Guess what? All can be attacked from inches, feet, or miles away. So can NFC.

        Your assertion about the correlation between distance and security might be correct, but your are incorrect about NFC vulnerabilities. It is extremely secure. If you have an example of when it has been hacked I’d be very interested.

    • Articles with Kill in it shouldn't be published

      NFC isn’t trying to solve prox. Data xfer with tags, secure payment yes, but I rarely see NFC and prox problems. Plus years and years of PCI developing protocols for NFC.

      Misdirection, like saying Bluetooth is going to kill Ethernet wireless. NFC and BLE don’t compete.
