Overview
NFC Key Fobs 5 pcs Gen2 CUID With Changeable UID 3.5 x 2.8 cm 13.56 MHz S50 1K For Writing Applications MCT on Android

A set of five NFC key fobs is designed for anyone who needs a chip with the ability to change its UID identifier. Each fob contains a Gen2 CUID chip, which is compatible with the S50 type with 1K memory and operates at a frequency of 13.56 MHz according to ISO 14443-A standards. Unlike standard chips with a fixed number, this design allows block 0, where the UID is stored, to be rewritten. You can write to it using an Android phone and NFC with the MCT application, so you do not need a separate writer. The fobs are a practical solution when you want to prepare a spare or backup chip.

The Gen2 designation means that block 0 is written using standard commands, and therefore the chip works with applications on your phone. The chip can take on the UID of another chip of the same type, and a reader that works with S50 1K chips will read it with the same identifier. In addition to block 0, you can also write data to other memory sectors, just like with a standard 1K chip. The compact droplet-shaped fob measures 3.5 x 2.8 x 0.4 cm and thanks to the metal ring, it can be easily attached to a keyring, keeping it always within reach.

  • Chip Type – Gen2 CUID compatible with S50 1K type
  • Frequency – 13.56 MHz (HF)
  • Standard – ISO 14443-A
  • Block 0 – writable, UID can be changed
  • Writing – Android phone and NFC with MCT application
  • Design – droplet-shaped fob with metal key ring
  • Dimensions – 3.5 x 2.8 x 0.4 cm
  • Package Contents – 5 NFC fobs with Gen2 CUID chip and metal key ring

Before writing, ensure that your system uses S50 1K chips at a frequency of 13.56 MHz. Chips of other types and frequencies, such as 125 kHz fobs, will not replace this fob. When rewriting block 0, proceed carefully and write data read from the original chip of the same type. Do not expose the fobs to high temperatures or bending to keep the chip inside undamaged. The five pieces in the package allow you to prepare multiple chips at once or have a reserve for later use.

The set of five NFC fobs combines small dimensions, a key ring, and a chip with a changeable identifier. Thanks to the chip with a writable block 0, you can set the UID as needed, and use the rest of the memory for your own data. Control via the MCT application on your Android phone is simple and does not require additional devices. The fobs are suitable for home, office, and workshop wherever S50 1K chips are used. The compact droplet shape fits into any pocket and onto any keyring.
