Personal identification system
First Claim
1. A personal identification system comprisinga card having a first recording means for permanently storing a first singularity which is unique to the authorized user of the card;
- a card reader;
a second recording means located on either the card or the card reader for temporarily recording a second singularity;
wherein said card reader further includes comparison means for comparing said first and second singularities and indicator means for indicating either a positive or negative result of said comparison means;
wherein said second recording means further comprises a plurality of recording areas, each of said recording areas capable of temporarily recording said second singularity upon presentation thereof, andsaid indicator means will not indicate a positive result from at least one but not all of said recording areas.

Abstract
A personal identification system wherein an encoded version of the user'"'"'s fingerprint is reprint is recorded on an identification card or device; this encoded version is security machine-read and directly compared at the time of use with an impression of the fingerprint on a different but designated area of the card, or alternatively on a designated area of the machine-reader or a separate card, the comparison being done on a one-to-one basis so as to reduce the need for a large memory or storage capacity for fingerprint records on the card or in the security machine-reader. The personal identification system can be used with passports, travellers cheques, credit cards, cheque cards and the like.

10. A method of personal identification comprising the steps of:
-
(a) issuing a card having a permanent record of a first singularity unique to an authorized user of said card, (b) providing a plurality of recording areas on said card, each of said recording areas capable of temporarily recording the singularity of the user of said card, (c) requiring the user to record the singularity on one of said recording means, (d) reading both said first singularity and said user'"'"'s singularity by means of a card reader, (e) comparing said first singularity with said user'"'"'s singularity, (f) determining whether said one recording area corresponds to the recording area designated according to a sequence stored in said card, and; (g) indicating a positive identification only if both steps (e) and (f) result in a positive comparison and determination, respectively.
