PayPal has announced that they're opening One Touch mobile payments to developers today, and the payment system will come to every PayPal user in the next few weeks. Even though PayPal only wanted to show off the payments on an iPhone, they're still coming to Android, rest assured. These mobile payments will work inside of applications to allow users to quickly make purchases by linking their PayPal accounts. Since it's PayPal, it can remember your bank accounts and credit cards and save you the headache of punching in numbers and information.
Since in-app purchases have been pretty controversial lately, PayPal will allow users to opt in or out of the experience at any time. Heavy Android users will probably want to stick to just using Google's in-app purchase system that's pretty universal across Android apps, but if you've got multiple devices split across mobile platforms, using PayPal can definitely be pretty handy to just maintain one balance for your apps instead of two or three.
It's going to take a few weeks for developers and merchants to update their apps to support PayPal's One Touch payments, but I'd bet it'll be pretty common by the end of this year.
