Google’s contactless payment solution, Android Pay, will now be available through the mobile checkouts of several Android apps in the U.S.
With this addition, it avoids having to pull out your card everytime you make a purchase, meaning card data never makes it to the merchants. A good news for anyone who is concerned about privacy.
Android Pay is compatible with all Near Field Communication (NFC) or Host Card Emulation (HCE) enabled devices using any OS released since KitKat.
With Coca-Cola signing up as the first merchant in the Google program, a new loyalty program was recently released for the mobile wallet, by tapping your phone on an NFC-enabled Coke vending machine, you’ll get a Coke and get points added into your Android Pay Account for future purchases.
