Many access control systems / RFID readers are now able to detect “Chinese Magic” tags by sending the “Unlock Command” (0x40 / 0x43). If the badge replies, it is flagged as an imposter / clone and rejected.

This is the Gen2 MF 1k S50 UID Changeable so it is different from the typical chinese tags / chinese backdoor command tags.

No magic backdoor command needed to change the UID.
