Cable lock UHF RFID three-state e-seal MYRMIDON SEAL

High security UHF RFID cable seal, automatic identification in radio frequency in the tamper evidence version, ISO 17712: 2013 certified



LeghornGroup MYRMIDON SEAL is a sturdy UHF RFID cable-lock seal that combines high mechanical security with the electronic security offered by RFID, automatic radio frequency identification technology.

It’s the first RFID cable seal – compliant with ISO17712 technical standards – available on the market that is able to provide its status information, UNLOCKED,  LOCKED or TAMPERED,  which is stored in the RFID chip. For this reason, the product has been named “three-state“.

The outer polypropylene plastic housing of the seal – customizable with mark and numbering on request – embeds an unique and latest generation of electronic chip, that has its own univocal coding, which cannot be replicated.

This allows for secure and reliable automatic identification of the seal applied to the container or vehicle.
