Abstract
An electronic toll collection (ETC) system has a problem that the system cannot issue a receipt at the time of use, because the system permits an ETC vehicle to pass a tollgate nonstop. The invention intends to solve the problem and provides a receipt-issuing device while ensuring security. In order to achieve it, the receipt-issuing device includes an IC card interface unit through which information is read out or written to an IC card, an SAM unit that enciphers information to be recorded in the IC card, and deciphers information to be read out therefrom, an operation unit that inputs an instruction of issuing a receipt, a printer unit that prints the receipt, and a control-processing unit that, when the SAM unit verified the security, permits an issue of the receipt by the printer unit. A requirement in the ETC history of use that the receipt is once issued is erased from the IC card, or the requirement is locked on data so that the receipt cannot be issued again to the same requirement.
