Google recently began issuing payment platform Android Pay to US users through Google Wallet app. The company says Android Pay now available in 1 million restaurants, shops and some other places in this country. In the future there will be many other enterprises to participate. Like Apple Pay, Android Pay also use NFC to connect phones with computer and automatically deducted from the user account after purchase. However, Pay is a platform and it is open to other third parties involved application development. Thus we may see Google Wallet is only used as an Android app Pay. In addition, Android also supports saving Pay membership information, discount cards, including even the "buy with Android Pay" to use on the web or app.Speaking of credit cards, Android Pay is supporting multiple banks such as American Express, Bank of America, Discover, Navy Federal Credit Union, PNC, Regions Bank, USAA, US Bank. Coming up will be Citi Bank and Wells Fargo.Android Pay require Android 4.4 or higher, NFC connectivity.
