The future of mobile payments --I have seen it, and its not with phone devices or physical proof of funds. It is with a simple phone number, and PIN like how Paypal does it. Everyone is talking about a device and scanning it at a counter (to leave wallets at home) but that is still an unnecessary step in the evolution. The way its gonna be, is already here, minus the mass awareness and implementation of it. You can leave both your wallet and your phone in your pocket! 1) Touch Pay with Paypal button on card reader. 2) Enter mobile cell phone number on numeric pad. 3) Enter 4 digit pin. 4) Take receipt. All this will do is make Paypal the most powerful way to pay on earth because Apple will bring awareness to it, and maybe it will take off, but as soon as the masses look into it, and try Paypal, and word gets out, it will be the thing that dominates the next decade, not an awkward phone scanning thing. The only reason Paypal Checkout isn't gaining momentum is because the mainstream doesn't know about it. (I used it at Home Depot and the cashier said he never saw someone use it before lol) It looks like this big push from Apple will change that. Not sure how it works with the software on most card readers in stores but if it takes off, all the merchants would need is a new pay with paypal button in the existing software vs NFC would need specialized hardware every time on a mass scale. It would be years until people start seeing them in all their favorite stores and setting up their iPhones to pay. But Paypal could just swoop in at some point one year if they can advertise it somehow.
