MIFARE Classic® 1K Compatible Blank UID tag - One Time Write UID

Need to make perfect, undetectable of MIFARE Classic® 1K Cards ?

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.

Exclusive to Lab401 - Our tag allows the UID to be set one time only - and after that - the tag never responds to magic commands. This allows you to make undetectable, perfect clones.

Once the UID has been set, the tag acts as a normal card. You can change the data of the card as many times as required - we've tested up to 10,000 read/write cycles. 

Remember: This badge's UID can only be set one time.

These tags are red and in key ring form for convenience.

Not all 'Magic' cards are alike. There are many chipset types, each with different levels of reliability and functionality. Lab401 has spent years sourcing, testing and visiting factories to find the most reliable and flexible 'magic' cards on the market.

IMPORTANT:

The UID of MIFARE Classic® Compatible 1K UID One Time Write tags is comprised of two parts: the UID itself, and the BCC. 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.

Lab401 cannot provide support or refunds under any circumstances for cards that were 'bricked' due to incorrect UID/BCC configuration.
