<P>PROBLEM TO BE SOLVED: To provide an unlocking system capable of improving work efficiency and convenience while maintaining high security. <P>SOLUTION: The unlocking system 100 comprises two IC cards (information recording media) 10 and a reader (an information processor) 20. The IC card 10 comprises a card communication part 11 which is in non-contact communication with the reader 20; a card control part 12 performing general control of the whole IC card 10; an RAM 13 used as a working area; an ROM 14 storing execution codes, card IDs, and the like; and an EEPROM 15 storing authentication data. The reader 20 comprises a reader communication part 21 which is in non-contact communication with the IC card 10, and a reader control part 22 which has an authentication part 23 allowing an IC card 10X to authenticate an IC card 10Y and allowing the IC card 10Y to authenticate the IC card 10X, and an unlocking part 24 unlocking a door lock when both authentications are successful in the authentication part 23, and performs the general control of the whole reader 20. <P>COPYRIGHT: (C)2007,JPO&INPIT |
