Abstract

A gaming machine includes an electronic gaming module which includes a game controller, and also includes a separate security interface module which monitors door switches and various devices. The security interface module has a separate unswitched power supply and also has a separate communication connection with a backend system so that it can continue to communicate with a backend system even when the electronic gaming module is powered down.

Claims

1. A method of operating a networked wager-based gaming machine comprising:

performing one or more security functions in an electronic gaming module, the electronic gaming module connected to a data network by a first data connection;

monitoring power provided to the electronic gaming module; and

in response to detecting a loss of power to the electronic gaming module, performing the one or more security functions in a security interface module, the security interface module connected to the data network by a second data connection, the security interface module receiving power separately from the electronic gaming module;

wherein, when the power is switched on to the wager-based gaming machine, the electronic gaming module and the security interface module perform the one or more security functions together.

2. The method of claim 1 wherein the one or more security functions include monitoring door switches.

3. The method of claim 1 wherein the one or more security functions include controlling employee access to the wager-based gaming machine when the power switch is off.

4. The method of claim 1 further comprising monitoring data provided by the electronic gaming module over the first connection, and data provided by the security interface module over the second connection, to identify discrepancies, and issue an alert in response to identification of a discrepancy.

5. The method of claim 1 further comprising reporting an unauthorized access to a component of the networked wager-based gaming machine to a backend unit through the second data connection.

6. A method of operating a networked wager-based gaming machine comprising:

performing one or more security functions in an electronic gaming module, the electronic gaming module connected to a data network by a first data connection;

receiving an alert from an external system indicating a loss of power of the electronic gaming module at a security interface module; and

in response to receiving the alert of the loss of power to the electronic gaming module, performing the one or more security functions in a security interface module, the security interface module connected to the data network by a second data connection, the security interface module receiving power separately from the electronic gaming module;

wherein, when the power is switched on to the wager-based gaming machine, the electronic gaming module and the security interface module perform the one or more security functions together.

7. The method of claim 6 wherein the one or more security functions include monitoring door switches.

8. The method of claim 6 wherein the one or more security functions include controlling employee access to the wager-based gaming machine when the power switch is off.

9. The method of claim 6 wherein the electronic gaming module performs the one or more security functions when power is switched on to the electronic gaming module.

10. The method of claim 6 further comprising monitoring data provided by the electronic gaming module over the first connection, and data provided by the security interface module over the second connection, to identify discrepancies, and issue an alert in response to identification of a discrepancy.

11. A method of operating a networked wager-based gaming machine comprising:

powering an electronic gaming module with a first electrical power source;

performing one or more security functions in an electronic gaming module, the electronic gaming module connected to a data network by a first data connection;

monitoring power provided to the electronic gaming module;

powering a security interface module with a second power source; and

in response to detecting a loss of power to the electrical gaming module, performing the one or more security functions in the security interface module, the security interface module connected to the data network by a second data connection;

wherein, when the power is switched on to the wager-based gaming machine, the electronic gaming module and the security interface module perform the one or more security functions together.

12. The method of claim 11 wherein the one or more security functions include monitoring door switches.

13. The method of claim 11 wherein the one or more security functions include controlling employee access to the wager-based gaming machine when the power switch is off.

14. The method of claim 11 wherein the electronic gaming module performs the one or more security functions when power is switched on to the electronic gaming module.

15. The method of claim 11 further comprising monitoring data provided by the electronic gaming module over the first connection, and data provided by the security interface module over the second connection, to identify discrepancies, and issue an alert in response to identification of a discrepancy.

16. The method of claim 11 wherein the second power source includes a battery.

17. The method of claim 11 further comprising reporting an unauthorized access to a component of the networked wager-based gaming machine to a backend unit through the second data connection.
