Abstract: An improved radio RFID tag and reader system comprising a reduced scale and scalable vehicle fitted with one or more electronic toll collection RFID tags and a track on which the vehicle may operate at a high rate of speed for long periods of time with minimal friction and without derailing or fatigue to the structure of either vehicle or track. The inventive testing system further utilizes a novel vehicle propulsion system comprising counter-rotating wheels adapted to maintain a variable and accurate speed of the vehicle upon each pass by the reader. The propulsion mechanism propels the vehicle down the track past the reader and returns it to a starting point to provide repeated interaction between RFID tag and reader.
