![]() R/W errors on some blocks can be either considered as critical or ignored. This bypasses authentication and allows reading of the Key A and Key B data regardless of ACLs. Similarly, the R option allows an 'unlocked' read. Currently only 4 byte UIDs are supported. ![]() Take care when amending UIDs to set the correct BCC (UID checksum). The W option allows writing of special MIFARE cards that can be 'unlocked' to allow block 0 to be overwritten. The f option to format the card will reset all keys to FFFFFFFFFFFF, all data to 00 and all ACLs to default. It uses a binary MIFARE Dump file (MFD) to store the keys and data for all sectors.īe cautious that some parts of a MIFARE Classic memory are used for r/w access of the rest of the memory, so please read the tag documentation before experimenting too much! It's possible to read and write the complete content of a MIFARE Classic 4KB tag within 1 second. This tool demonstrates the speed of this library and its ease-of-use. The firmware in the NFC controller supports authenticating, reading and writing to/from MIFARE Classic tags. MIFARE Classic tag is one of the most widely used RFID tags.
