I have a RFID-RC522 module that is connected to arduino micro. I want to send data from NFC of android mobile to that module. is that possible ? and if so, how can I perform that ?
Not possible, this reader barely supports reading/writing to Mifare Classic cards
It does not support Host Card Emulation or Peer to Peer or other standard cards.
A better module based on PN532 chip would be possible.
