Android NFC Card Emulation With Arduino MFRC522

QUESTION

Android NFC Card Emulation With Arduino MFRC522

Asked 2021-Feb-07 at 14:25

I am developing an android application creating NFC card ID. I can get info from scanned NFC cards by phone. But I can't create them with my app. First, I tried to do that with this method. Then, I realized need to have Tag object and tried to save it in different ways. Although it didn't work.

Secondly, I found this from android documentations. Then, I tried to do with HostNfcFService and HostApduService. To use them I created XML files and service classes like below;

nfcfservice.xml:

I think your problem is that the MFRC522 RFID reader is a very basic/old design and really only supports MIFARE type cards (which are the non standardised original card format). While Host Card emulation uses ISO/IEC 14443A (mostly) as a base it uses other higher level protocols to emulate a NFC Type 4 card which is not supported by that card reader.

If you look at an Arduino library for the reader https://github.com/miguelbalboa/rfid#troubleshooting

My mobile phone doesn't recognize the MFRC522 or my MFRC522 can't read data from other MFRC522
Card simulation is not supported.
Communication with mobile phones is not supported.
Peer to peer communication is not supported.

As the library suggest if you want more feature use a PN532 based modules instead.
