Title: Signature collating system
Inventor: HAYAZAKI AKIRA
IPC: G06K9/00
Filed: 1988-11-30
Abstract: PURPOSE:To prevent the wrong use due to forgery of signature by storing signature information of a medium owner in a portable storage medium as picture data and reading out and displaying this data by a terminal equipment at the time of the use to collate it with signature information written by the medium owner. CONSTITUTION:When a customer uses an IC card 11 for shopping, he transfers the card 11 to a clerk and signs his name on a slip received from the clerk and returns this slip to the clerk. The clerk inserts and sets the card 11 to a card reader/writer 12 and operates an operation part 15 of a terminal equipment 13 to read out picture data as signature information preliminarily stored in a data memory 18 of the card 11 and visually collates signature information 26 displayed on a display part 16 with the signature written on the slip by the card user to judge whether they are equal or not. Thus, the wrong use due to forgery of signature is prevented.
