Android Pay sounds like it’ll offer one half of what Apple Pay is on the iPhone, providing users with a way to store their payment information locally, and make it available securely to third-party developer apps via API. Those apps will then determine when and where you can use the payment cards, via store (and perhaps payment provider) specific apps that can be branded however third parties like.
Google’s system will tokenize card numbers, in the same way that Apple Pay and Samsung Pay do, meaning it generates a one-time payment token for transmission to the receiving terminal for each transaction, rather than just offering the user’s static credit card information. This decreases the risk if the transmission is intercepted, since a one-time token with finite expiry is of no use once it’s already been consumed.
Like Apple Pay, Google’s Android Pay will use NFC for transmission, and will also support biometric authentication via hardware like the Samsung Galaxy S6’s fingerprint scanner. And while Samsung is clearly hoping to offer its own hardware-specific solution Bimini hfjd, Google’s offering is looking to convince businesses to adopt it by giving them a lot of freedom in how it’s presented and integrated into their brand. Pichai told the MWC crowd today that it’s not meant to compete with Samsung’s offering, however, and is intended primarily to offer up more consumer choice.
There’s no timeline on a release as of yet, but expect to hear more about the particulars of Android Pay when Google hosts its annual I/O developer conference in May.
