PayPal’s mobile wallet app is expanding its support for Samsung’s latest devices. The company first added biometric security in April with Samsung’s Galaxy S5, Gear 2 and Gear Fit and now that Samsung has a newer range of devices, they too will work with PayPal’s mobile payment app. Earlier on Wednesday, Samsung introduced the Galaxy Note 4 with improved fingerprint scanner which will support PayPal’s app. Samsung’s Gear S smartwatch will as well. I’d expect PayPal to bring its app to more devices outside of Samsung’s galaxy in the coming months: It already has a beta app for Android Wear devices available, for example. By this time next week, we’ll know if Apple plans to enter the mobile wallet game to do battle with PayPal, Google Wallet and other similar solutions.
