Abstract

A fuel dispenser utilizing an application framework that comprises at least two portions, the first of which is configured to communicate with all devices, including those that handle confidential or sensitive customer data, while the second portion is configured to communicate only with devices that do not handle confidential or sensitive data. The application framework also comprises two frame buffers, one of which is only accessible by the first, secure portion. Additionally, the first portion determines which frame buffer is used by a display module to transmit data to a display in order to present a graphical representation of the data.

Claims

1. A fuel dispenser comprising:

a valve configured to facilitate a release of fuel by the fuel dispenser;

a processing device operatively connected to the valve;

a user interface comprising at least one input device and a display, wherein the processing device is operatively connected to the at least one input device and the display; and

memory operatively connected to the processing device and comprising an application framework that defines at least first and second frame buffers and includes a general purpose application and a secure payment application, wherein the application framework provides both the general purpose application and the secure payment application with access to the first frame buffer but prevents the general purpose application from accessing the second frame buffer and the secure payment application determines which of the first and second frame buffers may be used to present information via the display.

2. The fuel dispenser of claim 1 wherein the at least one input device comprises a first input device configured to receive payment information from a customer of the fuel dispenser, the application framework includes a first input device module configured to handle communication with the first input device, and the application framework prevents the general purpose application from accessing the first input device module directly but provides the secure payment application with access to the first input device module.

3. The fuel dispenser of claim 2 wherein the at least one input device comprises a second input device configured to receive non-confidential information from the customer, the application framework includes a second input device module configured to handle communication with the second input device, and the application framework provides both the general purpose application and the secure payment application with access to the second input device module.

4. The fuel dispenser of claim 1 wherein the application framework includes a display module operatively connected to the first and second frame buffers, to the display, and to the secure payment application, whereby the determination by the secure payment application of which of the first and second frame buffers may be used to present information via the display is effected by the display module.

5. The fuel dispenser of claim 1 wherein the general purpose application writes an advertisement to the first frame buffer.

6. The fuel dispenser of claim 5 wherein the secure payment application directs the display to use the first frame buffer so that the advertisement is presented by the display.

7. The fuel dispenser of claim 5 wherein the fuel dispenser is operatively connected to a server and the general purpose application receives the advertisement from the server.

8. The fuel dispenser of claim 1 wherein the secure payment application is configured to effect payment transactions for fuel dispensed by the fuel dispenser.

9. The fuel dispenser of claim 8 wherein the secure payment application is configured to effect the payment transactions based at least in part on payment information received from the at least one input device.

10. A payment terminal comprising:

a display;

memory; and

a processing device operatively connected to the display and the memory,

wherein the memory comprises an application framework that includes a plurality of applications, a plurality of modules, and a plurality of frame buffers, wherein each of the frame buffers is configured to store information to be presented by the display, and wherein, when executed by the processing device, the application framework provides a first of the plurality of applications with access to the plurality of modules and the plurality of frame buffers, provides a second of the plurality of applications with access to a first set of the plurality of modules and a first set of the plurality of frame buffers, and prevents the second application from accessing a second set of the plurality of modules and a second set of the plurality of frame buffers.

11. The payment terminal of claim 10 wherein the application framework provides the first application with the ability to select which of the frame buffers the display uses to present information.

12. The payment terminal of claim 10 wherein the application framework comprises a secure portion of an operating system and the secure payment application, the second set of the plurality of the modules, and the second set of the plurality of frame buffers is are stored on the secure portion.

13. An application framework for a payment terminal that comprises a display, memory, and a processing device, wherein the processing device is operatively connected to the display and the memory, and wherein the application framework is stored on the memory and comprises:

a general purpose application;

a secure payment application;

at least one input module configured to handle communication with at least one input device; and

a first frame buffer and a second frame buffer, wherein each of the frame buffers is configured to store information to be presented by the display, and

wherein the application framework, when executed by the processing device, is configured to cause the payment terminal to;

provide both the general purpose application and the secure payment application with access to the first frame buffer,

prevent the general purpose application from accessing the second frame buffer, and

provide the secure payment application with the ability to determine which of the first and second frame buffers is used by the display.

14. The application framework of claim 13 comprising a non-secure input module configured to handle communication with an input device configured to receive non-confidential information from a user of the payment terminal.

15. The application framework of claim 13 comprising at least one output module configured to handle communication with at least one output device, wherein the application framework, when executed by the processing device, provides both the general purpose application and the secure payment application with access to the at least one output module.

16. The application framework of claim 13 wherein the general purpose application is configured to request the secure payment application to use the first frame buffer.

17. The application framework of claim 16 wherein the application framework comprises an application interface and the general purpose application is configured to communicate with the secure payment application via the application interface.
