These passive transponders are designed to be used in applications where size and accessibility is a major criteria in identification.

The transponder is packaged in a range of materials to suit the environment required of specific applications. These transponders can be used in extreme temperature environments as well as conditions causing physical shock and vibration and still be fully functional.

Typical applications include:- liquid/chemical analysis, PCB marking, container/gas bottle marking, asset tracking, tree marking, access control and automobile security.

The transponder uses a magnetic RF coupling technique which allows it to operate embedded in plastics, wood, ice, greases as well as in metal containers. Powered remotely from the reader, the product has a very long usable life.
