# Digitize a card

### Overview

This section describes how to:

* Check if the card has been digitized in the issuer application
* Check if the device is eligible for NFC payment
* Digitize the card in the issuer application
* Check if the issuer application is ready for NFC payment (default payment application in Tap and Pay settings)

### User Experience

The end user can add eligible cards to the issuer application by opening the application and tapping the **Enable NFC payment** button.

The issuer application then displays an **NFC logo** if a card is digitized. The **NFC logo** will be grayed out if the issuer application is not ready for NFC payment.

The issuer application could be "not ready" for NFC payment for several reasons:

* issuer application is not the default payment application in Android Tap & Pay settings.
* the digital card has been suspended by the user or the issuer.

In conclusion, the issuer application displays different screens according to the card digitization state and the android settings.

### Implementation guides

To digitize a card, implement these steps in order:

1. [Check digital card state](/nfc-payment/implement-nfc-payment/digitize-a-card/check-digital-card-state.md)

   Check whether the card is already digitized.
2. [Check device is eligible](/nfc-payment/implement-nfc-payment/digitize-a-card/check-device-is-eligible.md)

   Check whether the device supports NFC payment before you show the digitization action.
3. [Add digital card](/nfc-payment/implement-nfc-payment/digitize-a-card/add-digital-card.md)

   Call the D1 SDK to digitize the card in the issuer application.
4. [Check Android Tap & Pay settings](/nfc-payment/implement-nfc-payment/digitize-a-card/check-android-tap-and-pay-settings.md)

   Check whether the issuer application is the default payment application.
