Google Pay is a digital wallet and online payment system 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.
Google Pay uses near field communication (NFC) to transmit card information from the user’s device to the merchant’s point-of-sale terminal, so users can make payments by simply tapping their device on the terminal. The service can be used to make payments in brick-and-mortar stores, as well as in apps and on websites.
Google Pay transactions are secure and private; when making a payment, users are not required to enter their personal or financial information, and their card numbers are not stored on their device or transmitted to the merchant. Google Pay also offers fraud protection and purchase protection for buyers.
