Both Apple Wallet and Google Wallet support contactless redemption of passes. The technology behind that is called Apple VAS and Google Smart Tap.
The common prerequisite is that you need a NFC reader that supports these protocols. The gifttowallet Smart Scan App supports a selected range of NFC readers but you can also choose to integrate readers from another vendor.
Please contact us if you need more details.
If your account is already enabled for NFC passes and you’re looking for instructions, check out this page.
