Google Wallet

Google Wallet holds your credit and debit cards, offers, and rewards cards. With this latest release, you can use any card from Visa, MasterCard, American Express, or Discover in conjunction with the app.
To pay in-store, select the card you want to use, and then just tap your phone to any contactless point of sale terminal. Payment information is transmitted via near field communication (NFC). Shortly after you’ll see a transaction record with merchant name and dollar amount on your phone.
Google Wallet keeps you safe and secure. The app has its own PIN, and if you lose your phone, you can remotely disable your mobile wallet from wallet.google.com/manage.
