Toy vehicle sets may include a toy vehicle with an RFID transponder operable to produce an identification signal to identify the toy vehicle and an RFID reader configured to generate an electromagnetic field, detect an identification signal produced by an RFID transponder, and produce data representative of the identified toy vehicle. In some embodiments, the toy vehicle includes circuitry adapted to convert electromagnetic energy into power to operate the RFID transponder. In some embodiments, the toy vehicle includes a metal chassis with an aperture configured to support the RFID transponder and a transverse slot cut from an outer edge of the chassis to the aperture.
