Abstract

Claims (54)

1. A system comprising:

a first gaming machine comprising a first input/output (I/O) device configured to generate a code based on a unique machine identifier of said first I/O device and a unique identifier associated with a voucher generated by said first I/O device;

a second gaming machine comprising a second I/O device communicatively coupled to said first I/O device via a network, said second I/O device comprising a voucher reader, said second I/O device configured to:

read the code from the voucher by said voucher reader;

parse the code to determine the machine identifier of said first I/O device;

transmit a validation request directly to only said first I/O device via said network using the machine identifier of said first I/O device and the unique identifier associated with the voucher;

receive a response message directly from said first I/O device, wherein the response message verifies the authenticity of the voucher presented at said second I/O device.

2. A system in accordance with claim 1 , wherein said first I/O device comprises a memory and a processor coupled to said memory, said processor configured to:

store the code in said memory area;

receive the verification request directly from said second I/O device; and

transmit the response message directly to said second I/O device.

3. A system in accordance with claim 2 , wherein said memory area is configured to store a plurality of unique voucher identifiers, said processor is further configured to:

parse the verification request to determine a voucher identifier of a voucher being verified;

compare the voucher identifier to the plurality of voucher identifiers stored in said memory area; and

determine from said memory area the number of credits available to the user if the voucher identifier matches one of the plurality of voucher identifiers.

4. A system in accordance with claim 1 , wherein said first I/O device is further configured to output the code on a voucher.

5. A system in accordance with claim 3 , wherein said second I/O device is further configured to apply the number of credits to a credit display for use by the user.

6. A system in accordance with claim 1 , wherein said second I/O device is configured to read the code from a voucher.

7. A first input/output (I/O) device for use with a gaming network, said first I/O device comprising:

a memory area;

at least one of a voucher printer, a voucher reader, and a combination voucher reader/printer and voucher reader communicatively coupled to a network interface; and

a processor coupled to said memory area and said network interface, said processor configured to:

read a code from a voucher using at least one of said voucher reader and said combination voucher reader/printer;

parse the code to determine a unique machine identifier of a second I/O device which originated the code on the voucher;

transmit a validation request by said at least one of said voucher reader and said combination voucher reader/printer via said network interface directly to only the second I/O device; and

receive a response message directly from the second I/O device, wherein the response message indicates approval to apply a number of credits available to a user to a credit display associated with the first I/O device.

8. The first I/O device of claim 7 , further comprising a scanning device configured to read the code from a voucher and to transmit the code to said processor.

9. The first I/O device of claim 8 , wherein said scanning device comprises one of a barcode scanner, a radio frequency identification (RFID) reader, and an optical reader.

10. The I/O device of claim 7 , wherein said processor is further configured to:

generate the code based at least in part on a unique machine identifier associated said I/O device;

store the code in said memory area;

receive the verification request via said network interface; and

transmit the response message via said network interface.

11. The I/O device of claim 7 , wherein said memory area is further configured to store a plurality of unique voucher identifiers, said processor is further configured to:

parse the verification request to determine an identifier of the voucher;

compare the identifier to the plurality of voucher identifiers; and

determine from said memory area the number of credits available to the user based on the identifier if the identifier matches one of the plurality of voucher identifiers.

12. The I/O device of claim 7 , wherein said I/O device is further configured to output the code on the voucher.

13. The I/O device of claim 12 , wherein said I/O device comprises a printer.

14. A method for verifying a gaming voucher using a first voucher input/output (I/O) device consisting of at least one of a voucher printer, a voucher reader, and a combination voucher printer and voucher reader and a second voucher I/O device consisting of at least one of a voucher printer, a voucher reader, and a combination voucher printer and voucher reader, said method comprising:

generating, by the first voucher I/O device, a code based at least in part on a unique identifier of the first voucher I/O device of a gaming machine and a unique identifier of the voucher;

storing the code in a memory area of the first voucher I/O device;

receiving, by only the first voucher I/O device, a verification request directly from the second voucher I/O device via a network;

determining, by the code in the memory area, a number of credits available to a player at the second voucher I/O device; and

transmitting a response message from the first voucher I/O device directly to the second voucher I/O device via the network, wherein the response verifies the authenticity of the voucher presented at the second voucher I/O device.

15. The method of claim 14 , wherein generating a code comprises generating the code based on the machine identifier, the issuance time and date of the voucher, and a unique voucher identifier.

16. The method of claim 14 , wherein storing the code comprises storing the code in the memory area in association with the voucher identifier.

17. The method of claim 14 , wherein determining a number of credits comprises:

parsing the verification request to determine a unique voucher identifier;

searching the memory area for the voucher identifier; and

determining the number of credits associated with the voucher identifier.

18. The method of claim 14 , further comprising outputting the code on a voucher.

19. The method of claim 18 , wherein the verification request is based on the second voucher I/O device reading the code from the voucher.

20. The method of claim 14 , wherein the code is generated at a conclusion of a play session by the player at the gaming machine.
