Trolley Scan Announces Development In RFID Technology


JOHANNESBURG,SOUTH AFRICA 24 OCTOBER 2005 Trolley Scan (Pty) Ltd, a Johannesburg, South Africa based developer of RFID (Radio Frequency Identification) technologies announced the development of an amazing new RFID technology that they have trademarked "RFID-radar". In the past RFID readers were limited to identify tags that were in the reader zone. Based around a major discovery made by Trolley Scan, RFID-radar based readers will now be able to identify, locate and track those same multiple tags in the reader zone.??Said Mike Marsh, Managing Director of Trolley Scan -"The breakthrough with RFID-radar is the ability to measure the distance travelled by a signal from a transponder to a reader accurately, over long distances, using minimal radio spectrum to minimize effects on other users, and with very low cost transponders and readers. This measurement allows us to identify, locate accurately and track the movement of tens of transponders in front of a reader at the same time.??In older generation RFID systems, operating ranges were a few centimeters, so location information was not important as the transponder was always close to the reader. In modern systems we have increased the operating range to tens of meters and will soon reach the one hundred meter range mark with passive tags.

Here location information together with the identity information becomes essential as so many transponders can be located in such a large area."??Said Marsh- "In the past it was not possible to measure the range of a transponder from a reader. The practicalities of UHF RFID mean that traditional approaches such as signal strength variation cannot be applied for range measurements. Our newly invented technique allows us to measure the range of a transponder to an accuracy of 0,5 meters and a pointing direction of just 1 degree, for transponders as far away as 100 meters, with up to 100 transponders in the zone at a time. This development is revolutionary, in that instead of needing expensive transponders and readers, our development allows this technique to be applied to the "US$five cent" transponder and the "US$100" reader. We make the measurements from a single reader site, making the equipment suitable for use in mobile applications such as when the reader is fitted to a forklift truck."??The new technology will result in the development of an entire new set of applications for computer based equipment. Applications could include the location of goods in a warehouse; tracking of individual animals in a herd; the monitoring of the movement of assets in a building; the location of parcels and airline luggage in a warehouse; the monitoring of children in a creche; or the monitoring of security zones to ensure secure areas are avoided.??The impact of RFID-radar technology on the future generations of RFID systems is going to be significant. Already more than 100 companies from all over the globe have contacted Trolley Scan about getting prototypes, commercial versions or OEM modules for incorporating into their own products. ??In the future there will be RFID readers that just give identity information, and there will be RFID-radar type readers that give identity, location and tracking information.

About Trolley Scan (Pty) Ltd
?Trolley Scan have proven to be a major creative force in the development of UHF RFID technologies. Founded in 1995, the staff of Trolley Scan have a pedigree that goes back to 1990 when the first low cost RFID protocol was developed by the founder while working for a South African government research organization, culminating in 1994 in the demonstration of a supermarket trolley containing 38 items being scanned automatically in a supermarket in Pretoria. In 1998, the founders of Trolley Scan developed an entirely new set of protocols for UHF RFID which they have been actively promoting. They also have addressed the situation of the 3 dimensional scanning of goods, and have developed a very low power RFID version which they commercialize under the EcoTag trademark.
?In August 2005 Trolley Scan invented RFID-radar. Trolley Scan are based in Johannesburg South Africa. ??Trolley Scan licence their patents and technology to companies around the world who wish to produce this technology. Trolley Scan sell RFID systems to users in 44 countries. Complete systems can be ordered via their website.
