You must complete the following prerequisites before you set up Smart Tap:

Pass development

You must complete REST API 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 Pay 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.
