There has always been a polarization among the users of the internet of things: those that understand and can manage the internet of things, and those who cannot. This phenomenon can in part be defined by those among us that can scan a QR Code and those of us who have tried and failed.
The modern-day equivalent of a blinking clock on a VCR, QR codes elude the majority of us. Just as we all recognized what the clock was for on a VCR, we all have the notion that a QR code contains information, a link perhaps, that can be used on the internet to gain access to even more information. But knowing what it is used for does not mean you know how to use it. How to scan it.
QR Codes are Dead, long Live QR Codes
But wait, aren’t QR codes dead? There are still those that feel that if used right, QR codes can be an effective means of communication. Back in 2011 comScore’s MobiLens service published a report showing that 1 in 3 individuals that scanned QR codes had a household income greater than $100,000. Looking to attract such a demographic, Taco Bell ran a successful campaign on ESPN where more than 225,000 QR codes were scanned. SnapChat has recently invested close to $51 million in QR code technology, according to Business Insider, in an effort to help increase those that use their service. Even music identification service Shazam is looking a using QR codes to increase the universe of what is Shazamable.
The problem with QR codes is not that they don’t work. They are very identifiable and just about everyone knows that you need to scan them. More and more we will see how QR codes can be used to do more than just provide a link to a web site as part of an advertising campaign. The problem that remains is that not everyone knows how to get them to work: how to scan or even create them. And that is just where the following apps can help:

Using their Coca-Cola Freestyle (Free, iPhone) app, you can customize your drink options even further by creating your own mix of flavors. You can add up to three different flavors and choose the proportions to create your own unique flavor; for example, ten percent Sprite, twenty percent Fanta zero raspberry, and seventy percent Hi-C orange (don’t judge me).
