Google Wallet's
Smart Tap technology lets
customers use any Pass they've saved to Google Wallet. They simply hold their phone to any
NFC point-of-sale terminal
to redeem their Pass.
For users to add a Pass, developers use the
Google Wallet API
to create a link or button. The link or button allows users to add 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.
Intended audience
This guide is for Google Wallet API developers who want their Passes to be redeemable via
NFC at a merchant's in-store terminal.
Prerequisites
You must complete the following prerequisites before you set up Smart Tap:
You must complete Pass development. To get
started, register your application.
It's necessary for you to develop a Pass so that you can configure it to be redeemable at an
NFC terminal via Smart Tap protocol.
Smart Tap capable terminals
To set up Smart Tap, you must either establish a relationship with a merchant that has Smart Tap
capable terminals, or work with a merchant to ensure that the terminals in their stores are Smart
Tap capable. A merchant can find a terminal provider whose terminals are Smart Tap capable at
Google Wallet Merchant Help.
You must also work with the merchant to ensure that the value in the Pass is conveyed correctly
to your system. Once the Point of Sale (POS) processes the value, make sure to
update the Pass
so that the user sees their new points balance or Pass status.
