iCS Decoder for iCLASS® SE / SEOS

iCS Decoder for iCLASS® SE / SEOS Decoder

The iCS Decoder for iCLASS® SE / SEOS is a specialized professional accessory designed exclusively for use with the iCopy-X RFID cloning platform. It is currently the only solution capable of decoding and cloning iCLASS® SE and iCLASS® SEOS credentials under supported system configurations.

The device connects directly to the iCopy-X and enables rapid decoding of protected iCLASS SE® and SEOS® badges. Once decoded, the system allows the creation of a legacy-compatible RFID card, provided the target access control system is configured to accept legacy formats—which remains the default in many deployments.

This capability makes the iCS Decoder an invaluable tool for authorized penetration testing, security audits, and law enforcement operations, opening a previously inaccessible attack and analysis surface within modern iCLASS environments. Operation is straightforward, fast, and fully integrated into the iCopy-X workflow.

Important Notes:

• The iCS Decoder functions only on systems that accept legacy cards.

• Coverage applies to approximately 85% of iCLASS SE® readers.

• The device is an accessory and requires iCopy-X to operate.
