MIFARE HANDLER

Designed to be used with an external ACR122U NFC Reader only.
The app can read and write MIFARE® Classic 1k/4k and Ultralight cards.

To read a MIFARE® Classic card:

1. Create a text file with authentication keys. Put the keys for each sector to a new line: KeyASector0, KeyBSector0, KeyASector1, KeyBSector1 etc. Have a look at the example screenshot.
2. Put the file to /MIFARE/auth.keys of your Android device.
3. Connect your ACR122U NFC Reader to your Android device with a cable.
4. Supply a card to the NFC reader.
5. The dump of your card will be saved to /MIFARE/READ/MIFARE_CLASSIC_1K/[UID].dump file, where UID - is the id of your card.

To write a MIFARE® Classic card:

1. Create a text file with authentication keys. Put the keys for each sector to a new line: KeyASector0, KeyBSector0, KeyASector1, KeyBSector1 etc. Have a look at the example screenshot.
2. Put the file to /MIFARE/auth.keys of your Android device.
3. Connect your ACR122U NFC Reader to your Android device with a cable.
4. Put the dump of your card to /MIFARE/WRITE/MIFARE_CLASSIC_1K/[UID].dump file, where UID - is the id of your card.
4. Supply the card to the NFC reader.

The process of reading and writing MIFARE® Ultralight cards is the same except that you do not need to supply auth.key as these cards do not support authentication. Use /MIFARE/*/MIFARE_ULTRALIGHT folders to read and write dump files.
