Card security system
First Claim
1. A method of enhancing security in a card security system having a card issuer and a card reader, comprising:
- a first recording step of recording at least first data onto an optically readable portion that is viewable on a first plane and contains a discrete visible holographic pattern formed to be reconstructed in a 2nd plane of a card;
an input step of inputting at least second data into the card issuer;
an obtaining step of obtaining check data based on at least the first and second data;
a second recording step of recording at least the check data to a storage medium which can be accessed by at least the card reader; and
a checking step of checking genuineness of the card by the card reader, based on at least data obtained by reading the optically readable portion of the card, data obtained from said storage medium, and the second data used in said input step.

Abstract
The object of the present invention is to effectively enhance card security in a system using identification card or the like. The card security system comprises a card issuing apparatus 100 and a card reader 300. The card issuing apparatus 100 obtains data D and E by reading hologram 2 and barcode 3 on a card 1. Data A, B and C are input from computer 200. An encryption unit 104 generates check data EN based on data A-E. A magnetic writer 103 write the data A-E and EN on a magnetic stripe 4. The card reader 300 reads data A-E and EN from the card 1, generates check data based on the read data A-E, and determines whether or not the card is genuine by comparing the calculated check data with the read check data EN.
