Validation systems for credit card or the like
First Claim
1. In a system where the owner of an information bearing card such as a credit card or the like is in the sole possession of a predetermined memorized number of a given number of significant digits, said credit card having on a surface thereof a plurality of first indicia corresponding to said predetermined number and a plurality of second indicia corresponding to a code determining how said first indicia is manifested on said information bearing card, in combination therewith apparatus for verifying that said number and said first indicia correspond, comprising:
- a. first means including a keyboard for storing said number after insertion thereby by an owner,b. second means responsive to both said first and second indicia on said credit card for providing at an output thereof an electrical signal according to said indicia,c. third means responsive to a digit of said number as stored to provide a first control signal and then responsive to only said second indicia for providing any one of a plurality of control signals each one operative to determine how said first indicia is to be translated,d. a plurality of translating means coupled to said second means, each one capable of responding to said electrical signal output representative of said first indicia to provide a decoded signal therefrom according to the particular format of said translator, each of said decoded signals representative of a digit contained in said predetermined number when translated according to said second indicia,e. translating selector means responsive to said control signals and coupled to said translating means to cause a first one of said translating means to be selected according to said first control signal and thereafter others of said translating means to be selected according to said plurality of control signals, whereby different selected ones of said translating means provide different digits of said number according to said second indicia on said credit card, andf. comparison means responsive to said decoded signals and said stroed number to provide an output when said decode signals correspond to said stored number, said output verifying that said memorized number and said first indicia on said card correspond.

Abstract
A credit card validation system employs apparatus which serves to decode validation information contained on the card by means selecting one of a plurality of translators selected at different intervals according to a predetermined format data also contained on the credit card. This uniquely translated information is compared with a secret subscriber number, memorized by the credit card holder, and obtained by him in complete privacy when his account is opened. .Iadd.
