Trolley Scan introduced their single chip version of their transponder systems in December 2003.

The Small system is a complete reader with 100 transponders.

The systems are supplied with one of two versions of their famous low power transponders - among the smallest, lowest power passive UHF transponders available anywhere in the world - and the super sensitive receiver capable of reading credit card sized transponders from 2 cms to 13 meters from the reader.The tags can also be attached to metal objects still giving full operating range.

The small "creditcard" sized (80mm by 35mm) Ecochiptag^tm version that needs just

• 200uW (two hundred microwatts) of RF energy to operate in countries that use the UHF spectrum for compatibility with the GSM cellphone network (such as Europe).
• 200uW (two hundred microwatts) of RF energy for US, Canada and countries that use the US spectrum plan.

These transponders offer operating ranges of up to 13 meters (even if attached to metal) depending on antenna, mounting and reader power.

The laundry tag version comprising a thin wire antenna, 16 cms long with a single chip transponder, needing just 1 milliwatt of RF energy to operate. The wire can be nearly as thin as a human hair making it suitable for attaching to clothing and laundry for automating processing of clothing.

The Ecowoodtag version is made to be attached to wooden objects such as pallets or furniture. The wood forms part of the antenna giving good performance.

These transponders offer operating ranges of up to 9 meters depending on antenna, mounting and reader power.

Trolleyponder is a Tag-talks-first protocol which causes virtually no interference for other users in the vicinity, having interference levels nearly 1 million times less than the reader-talks-first type protocols. Two Trolleyponder readers can operate simultaneously within a few meters of each other using only 10kHz of bandwidth each. These features are important for applications that require many readers to operate within a building.

(The system has no impact on or from Cell phones as it operates on different frequencies). The system is safe from a health point of view as the powers are much less than that experiences by users of cellphones
