Android EMV NFC Paycard Example

This sample program shows how to implement the library EMV-NFC-Paycard-Enrollment for reading the data on an EMC (CreditCard etc) with the NFC technology (contactless).

Source code: https://github.com/devnied/EMV-NFC-Paycard-Enrollment

The app uses the IsoDep class for communication with the NFC card and the enableReaderMode on the NfcAdapter for detecting a NFC tag; this mode is more reliable then the often used enableForegroundDispatch. see here for a more detailed explanation:

This app is getting just a small subset of all available data fields on an EMV card: typeName, aid(s), card number and expiration date of the card. The complete code is available here:

Don't forget to view the Logcat as the app gives a deep look to the commands and data that is exchanged between the Android device and the EMV card

As this app does not use any intent filter the data grabbing will work only if the app is in the foreground when the EMV card is detected.

The app was tested on a real device with Android 8 (SDK 26) and Android 12 (SDK 31).
