Google Pay is a digital wallet tied to your Google account. You can use it to send or request money with friends (kind of like Venmo), use it in apps to pay for things and use it at a store or restaurant with an Android phone or watch running Wear OS. But perhaps the real reason to use Google Pay is that it’s faster and more secure than using a physical debit or credit card.

Replacing Android Pay and Google Wallet in 2018, Google Pay works without sending stores and restaurants your actual card numbers. Essentially, your credit and debit card information is stored securely on Google’s servers, and instead of transmitting your card’s numbers, Google Pay uses a token called a virtual account number as a stand-in.
