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 two different code numbers, one of which is written on the card as the card number with the other being known to the proper owner of that card as its secret number. When a card is introduced into the system, the user of the card enters into the system its secret number by means of a dial or the like. There are provided in the system several types of operation, one of which is selected in accordance with the card number of the introduced card and the selected type of operation is conducted on the secret number. The result of the operation is compared with a predetermined number and when correspondence between the card number and the secret number is recognized on the basis of the result of the comparison, the user of the card is identified as the proper owner of that card.

Claims

1. A system for identifying the proper user of a card in a vending machine or the like;

said card having a first number recorded thereon, and a second secret number previously known to the proper owner of said card, comprising;

means for reading said first card number;

means manually operated by the user of said card to enter said second secret number into said system;

means for performing a predetermined operation on one of said first and second card numbers in accordance with an operation-typeselection number contained in the other of said first or second numbers; and

means for comparing the result of said operation and a predetermined number to produce an output signal when correspondence between said first and second numbers has been recognized on the basis of the result of said comparison.

2. The system of claim 1, wherein said operation performing means comprises a plurality of circuits for performing different types of operation and means operable in accordance with said operation-type-selection number to cause one of said plurality of circuits to perform one of said different types of operation on the other of said first and second numbers.

3. The system of claim 1, wherein said operation performing means comprises a plurality of circuits for performing different types of operation and means operable in accordance with said operation-type-selection number to cause one of said pluraliTy of circuits to perform one of said different types of operation on two numbers obtained from the other of said first and second numbers.

4. The system of claim 1, further including means for obtaining said predetermined number from either said first number or said second number.

5. The system of claim 1, wherein said operation performing means comprises a plurality of circuits for performing different types of operation and means operable in accordance with said operation-type-selection number to cause one of said plurality of circuits to perform one of said different types of operation on the other of said first and second numbers, and wherein said comparing means compares the result of said operation with a number obtained from said one of said first and second numbers containing said operation-type-selection number.
