Bolt-lock type High Security electronic seal working with active RFID technology



LEGHORNGROUP  has been dedicated to designing and producing mechanical security seals for the logistics sector. The dynamic company has a rich and well cultured background in anti tampering systems and the best means to tackle and prevent tampering or pilferage to your goods.

LEGHORN’s management team, aware of the importance of investing in projects that include electronic technology  have spent the last 10 years developing and expanding their current range of products. The latest products manufactured in house combine the traditional methods of mechanical tamper prevention with the most modern usage of RFID technology.

LEGHORN is proud to present their first single use active Rfid seal.

MENTORSEAL is an innovative seal that combines the high security of an ISO 17712:2013 approved seal, with the technical features of an active device that uses Radio frequency to automatically identify the container and/or vehicle.

The primary security  function of the seal is integrated with the possibility of improving the logistics  flow by keeping track of the container.

MENTORSEAL can be read with  static gateway readers of handheld portable readers, that are equipped with the relevant reading module of the seal- operating on a double frequency 433 MHz -2.45 GHz.

Thanks to the presence of active RFID , the seal can communicate over significant distances (e.g. over 15m).

The seal is characterised by it’s own unique Identification code. Furthermore as it is a single use seal its pricing is extremely competitive.

Some of the main innovative features of  MENTORSEAL are:

  • Guaranteeduniquenessof the coupling betweenthe head of theseal with thepinand barrel
  • Timestamp of when the seal is “born” stored in the memory;
  • Timestamp of when the seal is closed stored in the memory;
  • Timestamp of  the opening /or tampering of the seal stored in the memory.

DATA COMMUNICAITON: Any data received from MENTORSEAL using a hand held reader can be downloaded to a server whilst offline or alternatively online using WiFi or GPRS; If working with a fixed reader it can be connected to a PC via an Erthernet communication interface.


TRACEABILITY:  MENTORSEAL can store in its memory 15 Log  and the container ID.
This allows the user the trace the logistics flow of the container using the information received.


READING DISTANCE: MENTORSEAL  can be read at a distance of over 15 m by way of  “Contact reading” or “in line of sight”, allowing the reading to be taken whilst the container is in transit and speed up the security operations.
