Abstract
Abstract A system for identifying the proper user of a credit card or the like in a vending machine or the like. Each card used in the system is given an identification number and a key number both written on the card and a secret number previously known to the proper owner of the card. To make the secret number, the order or arrangement of the numerals constituting the identification number is changed or scrambled in accordance with a program as determined on the basis of the key number, and from the scrambled identification number some of the component numerals are removed in accordance with a program as determined on the basis of the key number, so that the remaining numerals are formed into the secret number of the card. When the card is used for a credit purchase, the system recognizes the secret number of the card from its identification number and key number in accordance with the above-mentioned programs, and then compares that secret number thus recognized with the secret number separately entered into the system by the user of the card. If the two secret numbers are found identical, the system recognizes the user of the card as its proper owner.
