The iCS Decoder is an iCopy-X accessory that allows for the rapid decoding and cloning of iCLASS SE® / SEOS® Decoder.

Until now, cloning of iCLASS SE® and iCLASS SEOS® has been impossible. With the iCS Decoder and iCopy-X – it’s as easy as cloning any standard RFID tag.

Most iCLASS® SE® & SEOS® systems still have legacy card acceptance enabled in their configuration. The iCS Decoder can decode iCLASS SEOS® IP / SE cards, and then generate an new card with legacy encoding.

For pentesters, the iCS Decoder exposes an entirely new in-scope attack surface. Likewise, LEA can use the device to make rapid clones in the field of a previously impossible badge type.

Please note:

  • The iCS Decoder will only work for target systems that are configured to accept legacy cards. This is the default configuration.
  • This technique will not work on all iCLASS SE® readers. Coverage is approximate 85%.
  • The iCS Decoder is an accessory – it requires an iCopy-X.


Setup and use of the iCS Decoder is rapid and simple.

  1. Plug the iCS Decoder into the iCopy-X using the provided USB-C Cable.
    The device will be automatically recognised. If it is not recognised after 5 seconds, unplug and replug the device.
  2. Place the target iCLASS SE® / iCLASS SEOS card® on the iCS Decoder.
  3. The iCopy-X will decode the card, and display the CSN, Facility Code and Card Number.
  4. Disconnect the iCS Decoder.
  5. The iCopy-X will prompt for a iCLASS SE® compatible tag (“iCS”)
  6. Place the blank card on the iCopy-X, and proceed with the write.
