Don't know how to change key of MIFARE MF1ICS50 card by using RC-522 and Arduino

[Anks3110]

Hello,

I'm using NFC MIFARE MF1ICS50 with RC-522 Reader/writer module with ARDUINO.

I can access the card but i don't get how to modify it's parameter,like how to change Key A and Key B of each sector, how to use and change access bits ?

can anyone tell me how it's works,and tutorial for learn this card and module.

Thank you,

Hello Ankit Ghevariya:

The documents on the next links should help you understand the memory structure, commands and use of the MIFARE Classic card:

http://www.nxp.com/documents/data_sheet/001056.pdf

http://www.nxp.com/documents/application_note/AN1304.pdf

For the Arduino part unfortunately I cannot help much since it uses code libraries not developed by NXP. We have the NFC Reader Library for these cases which is implemented with LPC microcontrollers.

However both parts are legacy (MFRC522 and MF1ICS50), so there must be for sure some code already available to manage MIFARE Classic cards with the Arduino board.

Best Regards!

Hello Jorge Gonzalez :

Thanks for your great help,

Now i'm studying AN1304 and i think it's very use full for understanding of key bytes and access bits.
