Get to Know Android PAY
With Android Pay, you can simply unlock your phone, place it near a contactless terminal, and pay for your items. You don't even need to open the app. When you shop at a merchant, Android Pay doesn't send your actual credit or debit card number with your payment. Instead, it uses a virtual account number to represent your account information—so your card details stay safe. You can even use Android Pay for in-app purchases, which means you don't have to enter your payment and address information.
Tap. Pay. Done.
