What is Google Wallet, how does it work, and which banks support it?

Google Wallet is the company's convenient payment system for Android users, previously called Android Pay.

Google Wallet is a rebranded mobile and online payments service, offering online payments, in-app purchases, and contactless payments in stores.
Setting up Google Wallet is easy - just download the app or use the preloaded version, add your card details, and start using it for convenient payments.
Google Wallet can do more than just payments - it can store tickets, rewards cards, and even support IDs, office badges, and digital car keys for a complete physical wallet substitute.
