How it Works:
Tying into the near field communication (NFC) system built into select Android handsets, Google Wallet allows your phone to act as your credit card. By tapping your Android phone against a compatible card reader available in select retailers, your payment credentials are transferred to the merchant without any swiping.
Google Wallet requires you to set up a Google Wallet PIN that must be entered before making a purchase. This PIN prevents unauthorized access and payments via Google Wallet. Android phones also feature a separate lock screen.
If your phone is stolen, Google Wallet PIN and Secure Element protect your payment card information which prevents
others making a purchase with your phone.
Google Offers are deals on products and services at local or online businesses. Whenever you buy or save a Google Offer, it automatically syncs to your Google Wallet so your offers are always with you.
