Android Pay

Android Pay is a digital wallet platform developed by Google to power in-app and tap-to-pay purchases on mobile devices, enabling users to make payments with Android phones, tablets or watches. Android Pay uses near field communication (NFC) to transmit card information facilitating funds transfer to the retailer. It replaces the credit or debit card chip and PIN or magnetic stripe transaction at point-of-sale terminals by allowing the user to upload these in the Android Pay wallet. It is similar to contactless payments already used in many countries, with the addition of two-factor authentication. The service lets Android devices wirelessly communicate with point of sale systems using a near field communication (NFC) antenna, host-based card emulation (HCE), and Android's security.

Android Pay takes advantage of physical authentications such as fingerprint ID where available. On devices without fingerprint ID, Android Pay is activated with a passcode. When the user makes a payment to a merchant, Android Pay does not send the credit or debit card number with the payment. Instead it generates a virtual account number representing the user's account information. This service keeps customer payment information private, sending a one-time security code instead of the card or user details.

Users can add payment cards to the service by taking a photo of the card, or by entering the card information manually. To pay at points of sale, users hold their authenticated device to the point of sale system. The service has smart-authentication, allowing the system to detect when the device is considered secure (for instance if unlocked in the last five minutes) and challenge if necessary for unlock information. Spring CEO Alan Tisch said Android Pay improves mobile shopping business by supporting a "buy button" powered by Android Pay integrated within vendor's creative design.

History
Android Pay was released at Google I/O 2015. Android Pay is a successor to and builds on the base established by Google Wallet which was released in 2011. It also uses technology from the carrier-backed Softcard—Google had acquired its intellectual property in February 2015. At launch, the service was compatible with 70% of Android devices, and was accepted at over 700,000 merchants. Google Wallet still powers web-based Play Store purchases and some app-based peer-to-peer payments, for instance in Gmail.

, it is currently available in the United States, UK, Canada, Ireland, Poland, Singapore, Australia, Hong Kong, Taiwan, Belgium, Japan, Russia and New Zealand. Upon its UK launch Android Pay supported MasterCard and Visa credit and debit cards from many of the UK’s major financial institutions — including Bank of Scotland, First Direct, Halifax, HSBC, Lloyds Bank, M&S Bank, MBNA and Nationwide Building Society — "with new banks being added all the time" according to Google.
