Abstract
An object checking system, particularly a signature checking system, verifies each card carrier by checking a signature entered from a tablet provided for a signature checking terminal device with a reference data stored in an IC card carried by the card carrier. The card is provided with a signature checker used to check the signature according to the checking algorithm corresponding to the reference data. The terminal device sends the hand-written signature to the card and receives the check result from the signature checker. Thus, the terminal device can verify the card carrier regardless of the type of the reference data stored in the card. In addition, only the signature checking program may be stored in the card, so that the terminal device reads the checking program to check the target signature or many signature checking programs may be stored in the terminal device in advance.
