Abstract

Methods and systems for preventing fraud by a customer at a fuel dispenser within a retail fueling environment are disclosed. According to one method, an authorization to access programming mode (AAPM) signal is received at the fuel dispenser from an authorization terminal coupled to the fuel dispenser. A request is received at the fuel dispenser to enter a programming mode of operation (PMO). The PMO is entered at the fuel dispenser to allow fuel dispenser settings of the fuel dispenser to be changed after receiving the AAPM signal and the request to enter the PMO.

Claims

1. A method for preventing fraud by a customer at a fuel dispenser within a retail fueling environment, comprising:

receiving an authorization to access programming mode (AAPM) signal at the fuel dispenser from an authorization terminal separate from the fuel dispenser;

receiving a request from a second terminal located at the fuel dispenser to enter a programming mode of operation (PMO); and

entering the PMO at the fuel dispenser to allow fuel dispenser settings of the fuel dispenser to be changed after receiving the AAPM signal and the request to enter the PMO.

2. The method of claim 1 further comprising preventing the fuel dispenser from being placed into the PMO prior to it receiving the AAPM signal.

3. The method of claim 1 further comprising measuring, in response to receiving the AAPM signal, a first time period.

4. The method of claim 3 further comprising determining whether the first time period has expired.

5. The method of claim 4 further comprising preventing the fuel dispenser from being placed into the PMO if a fuel dispensing transaction is initiated by the customer at the fuel dispenser or if the first time period has expired before the request to enter the PMO is received.

6. The method of claim 4 wherein measuring the first time period further comprises starting a timer to determine when the first time period has expired.

7. The method of claim 6 wherein starting the timer further comprises reading a current timer value of the timer and determining whether the first time period has expired further comprises comparing an elapsed period of time relative to the current timer value.

8. The method of claim 6 wherein the timer is selected from a group consisting of an up-counting timer and a down-counting timer.

9. The method of claim 6 wherein determining whether the first time period has expired further comprises an action selected from the group consisting of polling the timer and receiving an interrupt from the timer.

10. The method of claim 1 further comprising measuring a time period representative of a time that the fuel dispenser is in the PMO.

11. The method of claim 10 wherein measuring the time period further comprises starting a timer upon entering the PMO.

12. The method of claim 10 further comprising exiting the PMO if a request to exit the PMO has not been received by an expiration of the time period.

13. The method of claim 1 further comprising receiving a request to exit the PMO.

14. The method of claim 13 further comprising exiting the PMO.

15. The method of claim 1 wherein the authorization terminal is selected from a group consisting of a point-of-sale (POS) device, a site controller, a remote system, and a wireless device.

16. The method of claim 1 wherein the request to enter the PMO is received via a manager'"'"'s keypad located within a compartment of the fuel dispenser that is not accessible by the customer.

17. The method of claim 1 further comprising allowing programming parameters of the fuel dispenser to be changed while the fuel dispenser is in the PMO.

18. The method of claim 17 wherein the programming parameters include an operating mode, a drive-off warning, a transaction log enable setting, calibration values for the fuel dispenser, a zero price-per-unit (zero PPU) option, and PPU values.

19. The method of claim 1 further comprising selecting an AAPM protocol and wherein receiving the AAPM signal further comprises receiving additional signaling other than the AAPM signal in association with receiving the AAPM signal as part of the AAPM protocol.

20. The method of claim 19 further comprising receiving the additional signaling before the AAPM signal as part of the AAPM protocol to indicate that the AAPM signal is forthcoming.

21. The method of claim 20 wherein receiving the additional signaling before the AAPM signal includes receiving at least one pump stop signal before receiving the AAPM signal.

22. The method of claim 20 further comprising verifying proper receipt of the AAPM signal using the AAPM protocol.

23. The method of claim 19 further comprising receiving signaling after the AAPM signal as part of the AAPM protocol to indicate that the AAPM signal should have been received.

24. The method of claim 19 wherein the AAPM signal and the AAPM protocol are received from a point-of-sale (POS) device within the retail fueling environment.
