About Smart Tap

Google Pay's Smart Tap technology lets customers use any Pass they've saved to Google Pay. They simply hold their phone to any NFC point-of-sale terminal to redeem their Pass.

For users to save a Pass, developers use the Google Pay API for Passes to create a link or button. The link or button allows users to save various Passes to the Google Pay app. Types of Passes include loyalty cards, gift cards, offers, event tickets, boarding passes for flights, and transit passes. To make the Save link or button, see Add a web button.

Intended audience

This guide is for Google Pay API for Passes developers who want their Passes to be redeemable via NFC at a merchant's in-store terminal.
