Enhanced NFC Keyfob with Changeable UID and Writable Memory (10KeyCUID)

🧰 Introducing the GEN2 CUID Android App MCT Modify UID Changeable Tag Keyfob, available in sets of 5 or 10 pieces. These advanced NFC keyfobs operate at 13.56MHz and are built on the reliable 1k S50 standard, making them compatible with a wide range of NFC applications.

🌟 One key feature of these keyfobs is their unique programmability. Specifically, the Sector 0 Block Zero, known as the Serial Number or Manufacturer's Block (Chip CUID), can be reprogrammed to any UID you desire, offering enhanced customization for various security and identification purposes.

Each keyfob comes with a default password of FFFFFFFFFFFF for added convenience. However, please note that conventional 13.56MHz RFID reader/writers will not be able to write to the CUID cards. Instead, you’ll need to utilize an NFC-enabled Android device with the MCT app, or compatible readers such as ACR122U, PM5/Pro, 300CD, iCopy8, and Proxmark 3 to successfully modify the UIDs on these cards.

🧩 It's important to mention that the colors of the keyfobs will be randomly selected from our warehouse, and customization of colors is not available. Therefore, the keyfobs you receive may vary in appearance from the product images.

Upgrade your NFC solutions with these innovative and adaptable keyfobs, perfect for tech enthusiasts and professionals looking for reliable UID changing capabilities.
