Trolley Scan, a South African developer of RFID (radio frequency identification) technologies, has announced the development of a new passive transponder that has achieved an approximate 100% improvement in range over previous versions.
Announcing the development, Mike Marsh, managing director of Trolley Scan, said, "We have developed an amazing passive UHF transponder with a measured operating range of more than 25 metres. Bearing in mind that passive transponders do not have onboard energy, but have to collect energy radiated from the reader, a transponder that is passive and can work at 25 metres has to operate on minute amounts of radio power. In this case the transponder needs just 40 microwatts of radio energy in its collecting area. The transponder is specifically designed to be attached to metal and metal-like objects."
Previously, the maximum range possible with Trolley Scan’s passive transponders and readers was 13 metres. The impressive performance comes from the combination of a new integrated circuit specially made for Trolley Scan and from the company’s advanced RF antenna developments for transponders.
The new transponder has been specifically designed to be used with tracking laptop computers and office equipment, but also finds use in tagging metal items.
