Bolt lock UHF RFID three-state e-seal SOTER SEAL

UHF RFID bolt-lock seal, it can provide its status information, UNLOCKED,  LOCKED or TAMPERED,  which is stored in the RFID chip. Compliant with ISO 17712:2013



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

It’s the first RFID bolt seal – compliant with ISO 17712 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.

  • Has univocal ID code and read/write user memory capabilities.
  • It offers at the same time the immediate and accurate seal identification and the status of the seal i.e. unlocked/locked and evidence of tamper occurred, if any.
  • It is an ideal solution for guaranteeing cargo security and tamper evidence along the shipping and supply chain.


Unsurpassed security level built-in:
Any event that occurs to the seal (unlocked, locked and tampered) is permanently stored in its chip’s memory. Security is based on HW system– thanks to the technical specification of innovative chip RFID deployed – and it isn’t transferred to external SW systems and algorithms, as for competing products.
