Abstract

A system and method to adapt a fuel dispenser and related facilities to accept bar coded cards in addition to or instead of magnetic strip cards. A standard bar code reader is used in conjunction with a magnetic strip card reader. The bar code reader includes a light detector and a light source. The light detector and light source are secured so that they may visually access a card in the magnetic strip card reader. This allows the light detector to access bar coded data that is printed on a bar coded card. Furthermore, the addition of the bar code reader does not prevent the magnetic strip card reader from also reading a magnetic strip if it is present on the card. When a bar coded card is slid into the magnetic strip card reader, the bar code reader interprets the signals generated thereby and "decodes" the signals into corresponding numbers. These numbers are then sent over a data bus to a controller, where they are interpreted. Once interpreted, the numbers can be used similarly to numbers conventionally produced by a magnetic strip card, or can be used separately to provide additional services and/or advantages, such as updating a frequent purchase account.

Claims

1. A fuel dispenser comprising:

a nozzle for dispensing fuel;

a controller for selectively allowing the nozzle to dispense the fuel;

an optical reader connected to the controller for reading optical data provided by a user and transferring the optical data to the controller; and

a magnetic strip card reader connected to the controller for reading magnetic strip data provided by the user and transferring the magnetic strip data to the controller;

wherein, upon receipt of the optical data, the controller accesses a record associated with the optical data and allows the nozzle to dispense the fuel as part of a transaction, the terms of which are determined based upon the optical data received from the optical reader;

and wherein the optical data received from the optical reader identifies a purchase credit to be applied to the transaction.

2. A dispenser according to claim 1 wherein the record is a billing account to which an amount associated with the dispensed fuel is provided.

3. A dispenser according to claim 2 wherein the account is either a credit account or a debit account.

4. A dispenser according to claim 1 wherein the record designates a discount for adjusting a price associated with the dispensed fuel.

5. A dispenser according to claim 1 wherein the record stores information from the dispensing for later retrieval.

6. A dispenser according to claim 1 wherein the optical reader is a bar code wand.

7. A dispenser according to claim 1 wherein the optical reader is an optical scanning device.

8. A dispenser according to claim 1 wherein the optical reader and the magnetic strip reader are connected to the controller through individual buses.

9. A dispenser according to claim 1 wherein the record designates a discount for adjusting a price associated with the dispensed fuel and the magnetic strip reader is used to update a billing account to which an amount associated with the dispensed fuel is provided.

10. A dispenser according to claim 1 wherein the optical reader is an optical scanning device located on a front face of the dispenser.

11. A dispenser according to claim 10 wherein the optical reader is also capable of reading optical data from items other than bar coded cards.

12. A dispenser according to claims 1 wherein the magnetic strip data received from the magnetic strip card reader identifies payment arrangements for the transaction after application of the purchase credit.

13. A fuel dispenser comprising:

a nozzle for dispensing fuel;

a controller for selectively allowing the nozzle to dispense the fuel;

an optical reader connected to the controller for reading optical data provided by a user and transferring the optical data to the controller; and

a magnetic strip card reader connected to the controller for reading magnetic strip data provided by the user and transferring the magnetic strip data to the controller;

wherein, upon receipt of the optical data, the controller accesses a record associated with the optical data and allows the nozzle to dispense the fuel as part of a transaction, the terms of which are determined based upon the optical data received from the optical reader;

and wherein the optical data received from the optical reader identifies a discount to be applied to the transaction.

14. A dispenser according to claim 13 wherein the magnetic strip data received from the magnetic strip card reader identifies payment arrangement for the transaction after application of the discount.

15. A system for dispensing fuel responsive to the receipt of bar coded data and magnetic strip data and securing payment therefor, the system comprising:

a first reader for receiving the bar coded data;

a second reader for receiving the magnetic strip data;

a controller for receiving the bar coded data from the first reader and the magnetic strip data from the second reader;

at least one database responsive to at least the bar coded data for determining terms under which fuel is to be dispensed and returning a control signal to the controller, the control signal containing commands selected such that the fuel is dispensed in accordance with the terms; and

a dispenser for dispensing the fuel responsive to issuance of the commands by the controller;

wherein the bar coded data received from the first reader identifies a purchase credit and the database incorporates the purchase credit into the terms under which fuel is to be dispensed.

16. A system according to claim 15 wherein the database contains a customer profile for a customer of the system.

17. A system according to claim 16 wherein the bar coded data is used to access the customer profile and the magnetic strip is for indicating a payment account for the dispensed fuel.

18. A system according to claim 16 wherein the first reader includes an optical wand for reading the bar coded data.

19. A system according to claim 15 wherein the first reader includes a scanning bar code detector.

20. A system according to claim 19 wherein the scanning bar code detector is on a front face of the dispenser.

21. A system according to claim 19 wherein the scanning bar code detector is on a kiosk connected to the dispenser.

22. A system according to claim 19 wherein the scanning bar code detector is capable of reading bar coded receipts.

23. A system according to claim 15 further comprising:

a customer interface for receiving the commands and communicating information responsive to receipt of the commands.

24. A system according to claim 23 wherein the information responsive to receipt of the commands indicates a customer reward.

25. A system according to claim 24 further comprising:

a carwash facility and wherein the customer reward is a carwash at a reduced price.

26. A system according to claim 24 further comprising:

means for communicating to the carwash facility the existence of the customer reward.

27. A system according to claim 15 wherein the magnetic strip data received from the second reader identifies payment arrangements and the database incorporates the payment arrangements into the terms under which fuel is to be dispensed.

28. A system for dispensing fuel responsive to the receipt of bar coded data and magnetic strip data and securing payment therefor, the system comprising:

a first reader for receiving the bar coded data;

a second reader for receiving the magnetic strip data;

a controller for receiving the bar coded data from the first reader and the magnetic strip data from the second reader;

at least one database responsive to at least the bar coded data for determining terms under which fuel is to be dispensed and returning a control signal to the controller, the control signal containing commands selected such that the fuel is dispensed in accordance with the terms; and

a dispenser for dispensing the fuel responsive to issuance of the commands by the controller;

wherein the bar coded data received from the first reader identifies a discount and the database incorporates the discount into the terms under which fuel is to be dispensed.

29. A system according to claim 28 wherein the magnetic strip data received from the second reader identifies payment arrangement after application of the discount and the database incorporates the payment arrangements after application of the discount into the terms under which fuel is to be dispensed.
