Abstract
A system for issuing ID cards to which personal information data such as a personal identification number are written and verifying whether or not the information data are successfully written to the ID card. When the information data are confirmed to be unsuccessfully written to the ID card as the result of verification, the card is regarded as a faulty card, and an erase signal is automatically overwritten to the faulty card before discharging the card out of the system, so as to ensure absolute secrecy of the personal information.
