Trolley Scan has been granted its key protocol patent that is the basis of the Trolleyponder RFID system by the European Patent Office. The grant is effectively backdated to 1998 when the invention was filed in the patent processing system.
The patent allows many simple transponders to communicate with a reader using a single communication channel and forms the basis for scanning systems such as would be needed when scanning the contents of a supermarket trolley in a store. It allows all transponders to even carry identical information data such as is needed in a system designed as a bar code replacement solution, while also allowing anti-shoplifting (EAS) features to be included in the system.
The patent has already been granted in the US and many other countries.
