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.
