An RFID system such as the Trolleyponder system allows

Although the system was designed around the Trolleyponder RFID system, the actual model as built did not use an RFID system due to lack of time as this was a limited project.

Besides building the physical model to be compatible with the RFID system, Saira wrote the software to control the scanner and integrate the application into the management system of a small store.

Tests were carried out with members of the public operating the system to get feedback on the machine/human interface.
