Overview
NFC Key Fobs 10 pcs With Gen2 CUID Chip Rewritable Block 0 and UID 3.5 x 2.8 cm 13.56 MHz S50 1K For MCT Application

A pack of ten NFC key fobs is ideal wherever you need multiple chips with the ability to change the UID identifier. Each fob contains a Gen2 CUID chip compatible with the S50 type with 1K memory, which communicates at a frequency of 13.56 MHz according to the ISO 14443-A standard. Unlike standard chips, which have a fixed number set at manufacture, it also allows rewriting of block 0 containing the stored UID. To write, you only need an Android phone with NFC capability and the MCT application; no other devices are required. A larger pack is useful for preparing several spare or backup chips at once for the whole family.

Second generation Gen2 chips accept writing to block 0 using standard commands, so they can be modified by an application on a mobile phone. The fob can thus take on the UID of another chip of the same type, and a reader working with S50 1K chips will read the same identifier. Custom data can be written to other memory sectors just like with a standard 1K chip. The drop-shaped fob measures 3.5 x 2.8 x 0.4 cm and features a metal ring, making it easy to attach to keys or a carabiner.

  • Chip – Gen2 CUID compatible with S50 1K type
  • Operating Frequency – 13.56 MHz (HF)
  • Standard – ISO 14443-A
  • Block 0 – rewritable, UID can be changed
  • Writing Method – Android phone with NFC using the MCT application
  • Shape – drop shape with a metal keyring
  • Dimensions – 3.5 x 2.8 x 0.4 cm
  • Contents of Package – 10 NFC fobs with Gen2 CUID chip and metal keyring

Before you start writing, ensure that your system works with S50 1K type chips at a frequency of 13.56 MHz. Fobs with a different frequency, such as 125 kHz, or other types of chips cannot be replaced with this fob. Rewrite block 0 judiciously and use data read from the original chip of the same type. Protect the fobs from high temperatures and bending to keep the chip inside functional. Ten pieces in the package give you a sufficient reserve for additional chips and in case of loss.

The pack of ten NFC fobs combines compact dimensions, a practical ring, and a chip with a changeable identifier. Thanks to the rewritable block 0, you can set the UID yourself and use the remaining memory for your own data. Writing via Android phone is quick and does not require any separate writer. The fobs can be used at home, in the office, or in a business where S50 1K chips are used. You will appreciate having a larger number of pieces when you want to have chips prepared for more people or more locations.
