Google previewed its upcoming Android M at the Google I/O conference yesterday. This new Android version introduces a new permission model, new power management features, support for USB Type-C, custom browser tabs, etc. Full details can be found at the Android Developers blog.
One of the bigger improvements is Android Pay, a new payment system that works via near field communication (NFC). The system is linked to your Visa or MasterCard, it has support for fingerprint recognition and promises a simple "tap and go" experience:
With Android Pay, you can simply unlock your phone like you normally do, place it near a merchant’s contactless terminal, and you’re good to go. Android Pay does all the heavy lifting. You don’t even need to open an app—just tap and go. You’ll also see a payment confirmation and get transaction details right on your phone.
Also, with select retailers, your loyalty programs and special offers will be automatically applied at checkout. For example, when you tap to buy a Coke at a vending machine, your MyCokeRewards will be automatically applied. With Android Pay the contactless terminal not only receives your payment info, but also your loyalty programs and offers.
