Can I use Google Wallet as backup when I lose my card?

Your phone uses Near Field Communications (NFC) to communicate with the terminal and so you may not need an internet connection to use the Google Wallet app in stores.

Due to the nature of NFC, you may however be prompted to connect to the internet if you have not done so for an extended period of time to ensure you can use the app in stores.
