# Use cases

The IDEMIA Tap & Pay service covers the following use cases:

- The IDEMIA Tap & Pay service enables cardholders to have a digital version of their payment card in a mobile banking app to **pay by tapping** their Android phone at NFC-enabled POS terminal, in store. In this use case the payment performed is considered as a **card-present transaction** (proximity payments).
- In addition to proximity payments with merchants, the IDEMIA Tap & Pay service could be used for **EMV transit use case** thanks to the offline data authentication capability (both for closed and open loop configuration).
- The IDEMIA Tap & Pay service could also be used for in-app payments. This use case is relevant in the contact of **private label card issuers** who could drive the adoption and integration of this in-app payment options with **participating merchants**.
