Abstract

A cash dispensing system having a central computer and associated memory for maintaining customer account records, a plurality of remote transaction terminals and a communication path connecting the remote terminals with the computer. Each of the remote terminals includes a signal generator for generating data representative of a desired transaction in response to a customer-initiated operation, and for transferring that data to the computer via the communication path. The computer includes means responsive to the transaction data to generate a customer information file (CIF) signal and to transfer that signal to the remote terminal. The CIF signal is representative of a predetermined number associated with the customer. Each remote terminal includes a cash dispensing apparatus which includes a personal identification number (PIN) signal generator, a security device, a PIN signal transfer means, a CIF signal receiving means, and a cash dispenser. The PIN signal generator provides a PIN signal in response to a manual operation performed by a customer, with the PIN signal being representative of a predetermined number associated with the customer and bearing a predetermined relationship to the CIF signal. The security device includes the comparator for generating a DISPENSE signal when an applied PIN and CIF signal bear the predetermined relationship. The PIN signal transfer means provides a direct signal path for the PIN signal from the PIN signal generator to the security device. The CIF signal receiving means provides a means for receiving a CIF signal from the computer by way of the communication path and for transferring that received signal to the security device. The cash dispenser includes a cash storage portion and a dispensing mechanism for dispensing one or more units of the stored cash in response to applied DISPENSE signals.

Claims

1. A cash dispensing system having

a central computer and associated memory and computer signal transfer means, for maintaining customer account records,

at least one remote transaction terminal, and a communication path interconnecting said remote terminal with said computer,

wherein each of said remote terminals includes means for generating a transaction data signal representative of a desired transaction in response to a customer initiated operation, and for transferring said transaction data signal to said computer, and wherein said computer signal transfer means includes means responsive to said transaction data signal from a remote terminal to generate a multiple bit customer information file (CIF) signal and to transfer said CIF signal to said remote terminal via said path, said CIF signal being representative of a predetermined multiple bit CIF data word associated with said customer, and said remote terminals include a cash dispensing apparatus comprising:

A. input means comprising a personal identification number (PIN) signal generator for generating a multiple bit PIN signal in response to a manual operation performed by said customer, said PIN signal being representative of a predetermined multiple bit PIN data word associated with said customer and bearing a predetermined relationship to said CIF signal,

B. a security device including a comparator means, said comparator means being responsive to said PIN and CIF signals to generate a DISPENSE signal only when said PIN and CIF signals bear said predetermined relationship,

C. transfer means comprising a PIN signal transfer means for transferring said PIN signal directly to said security device,

D. receiving means comprising a CIF signal receiving means for receiving said CIF signal as transferred from said computer and for transferring said received CIF signal to said security device, and

E. a cash dispenser for storing cash units and dispensing one or more of said cash units in response to said DISPENSE signal.

2. System according to claim 1 wherein said input means further includes:

A. means for generating a BIT signal representative of the number of bits in said PIN signal, and

said transfer means further includes;

B. bit signal transfer means for transferring said BIT signal from said remote terminal to said computer via said path, and

wherein each customer record includes a BIT data representative of the number of bits in said PIN data word associated with that customer, and wherein further said computer signal transfer means includes means responsive to said BIT signal to initiate said transferral of said CIF signal to said remote terminal when said BIT signal corresponds to said BIT data and to inhibit said transferral otherwise.

3. System according to claim 2 wherein said input means further comprises:

a card reader having a transducer for generating a CARD signal as a customer-inserted card is driven past said transducer, said CARD signal being representative of a CARD data word encoded on said card,

wherein said CARD signal comprises an OFFSET signal, said OFFSET signal being representative of a predetermined multiple bit OFFSET data word, and bearing a predetermined relationship to said PIN and CIF signals.

4. System according to claim 3 wherein said transfer means further comprises an OFFSET signal transfer means for transferring said OFFSET signal directly to said security device.

5. System according to claim 4 wherein said comparator means is operative to generate said DISPENSE signal only when said PIN, CIF, and OFFSET signals bear said predetermined relationship, and said comparator means is inoperative otherwise.

6. System according to claim 3 wherein said transfer means further comprises an OFFSET signal transfer means for transferring said OFFSET signal to said computer.

7. System according to claim 6 wherein said computer includes means responsive to said OFFSET signal to generate a COMBINED signal from said CIF and OFFSET signals and to transfer said COMBINED signal to said remote terminal.

8. System according to claim 7 wherein said receiving means further comprises a COMBINED signal receiving means for receiving said COMBINED signal from said computer and for transferring said received COMBINED signal to said security device, and wherein said comparator means is operative to generate said DISPENSE signal only when said PIN signal and the CIF and OFFSET signals of said COMBINED signal bear said predetermined relationship, and said comparator means is inoperative otherwise.

9. System according to claim 1 wherein said input means further comprises:

a card reader having a transducer for generating a CARD signal as a customer-inserted card is driven past said transducer, said CARD signal being representative of a CARD data word encoded on said card,

wherein said CARD signal comprises an OFFSET signal, said OFFSET signal being representative of a predetermined multiple bit OFFSET data word, and bearing a predetermined relationship to said PIN and CIF signals.

10. System according to claim 9 wherein said transfer means further comprises an OFFSET signal transfer means for transferring said OFFSET signal directly to said security device.

11. System according to claim 10 wherein said comparator means is operative to generate said DISPENSE signal only when said PIN, CIF and OFFSET signals bear said predetermined relationship, and said comparator means is inoperative otherwise.

12. System according to claim 9 wherein said transfer means further comprises an OFFSET signal transfer means for transferring said OFFSET signal to said computer.

13. System according to claim 12 wherein said computer includes means responsive to said OFFSET signal to generate a COMBINED signal from said CIF and OFFSET signals and to transfer said COMBINED signal to said remote terminal.

14. System according to claim 13 wherein said receiving means further comprises a COMBINED signal receiving means for receiving said COMBINED signal from said computer and for transferring said received COMBINED signal to said security device, and wherein said comparator means is operative to generate said DISPENSE signal only when said PIN signal and the CIF and OFFSET signals of said COMBINED signal bear said predetermined relationship, and said comparator means is inoperative otherwise.
