The BCC is a checksum value calculated from the UID. If the BCC is incorrect, tag will be rejected by the reader.Most RFID tools, such as the Proxmark, LibNFC, MCT etc automatically calculate the BCC when the UID is modified. If you are modifying the UID by hand, it is vital that the BCC is correctly calculated.KSEC cannot provide support or refunds under any circumstances for cards that were ‘bricked’ due to incorrect UID/BCC configuration.
