Amongst the new features on Samsung’s new s5 is fingerprint authentication. It didn’t get much attention, though, because at first it seemed like a simple catch-up to Apple’s developments. Nonetheless, it turns out that Samsung partnered with PayPal to develop a unique encrypted key that lets PayPal verify users’ identities via the fingerprint authentication, and thus pay with PayPal from the phone. With the simple swipe of a finger to authenticate identity, PayPal users can use the phone as their wallet. Though Apple is behind, they’ve made noise about fingerprint-authenticated payments as well – they’ve got one of the largest credit card repositories on the planet at the moment; all they need to do is leverage it. At the moment, though, Samsung’s beat them to it.
