RFID Device (Two-piece Device for Tolling Application) The system consists of a two-piece structure of RFID tag, comprising an RFID card and the card slot. The unique identity of the driver’s tolling account is kept in the standalone RFID card with a short-read range of around 3 cm. Once the card is put into the card slot, the amplifying antenna in the card slot will couple with the RFID card, extending the read range to more than 6 metres. LSCM also designed a magnetic locking feature in this two-piece tag device which facilitates the application in tolling systems. To suit the application in commercial vehicles with multiple drivers, the two-piece tag device can easily differentiate different drivers, while the RFID card can also serve as the driver's identity card. In the tolling application, information of both the drivers and vehicles can be collected simultaneously in each transit. This solution has won a Silver Medal in the 48th International Exhibition of Inventions of Geneva.
