An automatic toll collector has a portion installed at an entrance toll gate and a portion installed at an exit toll gate of a toll road. Each portion has a decoder which recognizes information on the license plate of a vehicle entering the toll gate, and a read and write mechanism which reads and writes into an IC card information necessary for the collection of tolls. The driver of the vehicle inserts the IC card into one of the read and write mechanisms at each toll gate and carries the IC card with him as he travels along the toll road. At the exit toll gate, a comparing and toll calculating mechanism calculates the toll based on the information stored on the IC card. A toll withdrawal mechanism at the exit gate automatically withdraws the toll from a bank account which is indicated by the information stored in the IC card.
