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.

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.
