Hi, I need to read data from the 1K memory of an rfid tag with RC 522 , write a text a text in to the tag with exemple write_personal_data from the library but i can read data from the it with the read_rfid_exemple from the library it read just 32  not all the caracters.
I need to read all data from the tag .


Which MFRC522 Library you are using? Download its library from Arduino website and it has all the basic examples to get complete data from RFID cards.


Yes i try but it read me just 2 blocks of 16 caracters and I dont know how to extend it to all sectors / blocks
