Android Pay works at over one million locations (and counting…) across the US and in your favorite Android apps.
Your actual card number isn’t shared with the merchant when you use Android Pay. Instead, a virtual account number is used so that your card details stay safe. After paying, you’ll receive transaction details to help you keep track of your spending activity. And if your phone is ever lost or stolen, you can lock your device from anywhere using https://myaccount.google.com.
