A news service reporting on developments regarding the use of radio based tagging transponder systems for commerce and scientific applications. Covering RFID and EAS technologies as well as magnetic/electric field coupled techniques.


The biggest and fastest item to be scanned with low cost RFID

Trolley Scan of South Africa, the developers of the Trolleyponder and EcoTag© UHF RFID technology, report that one of their users have scanned at speed the largest item ever to pass through an RFID scanner system, at the highest speed, that is ever likely from a technology that was ultimately developed to scan items in a supermarket.

Fastening the transponder to the undercarriage, the antenna system with tie downs to the runway, and linking a triggered camera to record the actual moment the reader correctly identified the transponder, this company managed to identify using RFID a Lear jet at the moment of takeoff, at speeds in excess of 300 kph.

Airborne at last

Trolleyponder/Ecochip technology is used for very fast applications as it is based around a TTF (tag talks first) protocol where the transponder initiates the communication when entering the energy field, and the reader manages the multi transponder communications. Despite using only 10 kilohertz of operating bandwidth, and being very environmentally friendly with regard to interference generating that might impact other users close by, the system in theory can operate at speeds as high as Mach 2.

This high speed application demonstrates why Trolleyponder/Ecotag is used in many applications wher transponders have to move fast, such as toll roads, vehicle control, sports timing and the like.

With this test, the record for the largest item ever tagged and read at full operational speed is claimed. More info on Tolleyponder products can be obtained from Trolley Scan at http://trolleyscan.com
