Abstract
A vehicle-carried unit for automatic toll-paying systems carried on a vehicle for automatically paying a toll from a plurality of IC cards through communication with an on-road unit installed on a road. The toll is calculated at an exit gate in accordance with predetermined toll information (step 432), and it is judged whether or not payment is possible in accordance with balance information of a plurality of IC cards stored in a storage circuit (step 434). In the case of being capable of payment, the toll is subtracted (step 486), and a payment signal is transmitted to the on-road unit (step 488). Because balances of a plurality of IC cards are stored as described above, it becomes unnecessary to stop at a tollbooth due to shortage in balance.
