Android Pay to get Visa Checkout and Masterpass compatibility for mobile shopping
According to Google, Android Pay's open platform will also make payment integration easy for merchants and developers. For example, merchants who activated Visa Checkout or Masterpass on their sites will have payment buttons updated automatically to correspond with Android Pay.
Alas, it will take a while before the integration is fully complete. Google says we should expect the Visa and Masterpass-compatible Android Pay in early 2017.
