20110134044 | FUEL DISPENSER USER INTERFACE - A user interface for a fuel dispenser comprising a display, a display controller, and control circuitry. The control circuitry comprises a processing device, memory, and at least one microswitch. The display controller and the control circuitry are positioned such that the microswitch connects the control circuitry to the display controller. The microswitch is activated if the control circuitry is separated from the display controller. Activation of the microswitch causes any sensitive information stored by the control circuitry to be erased. In one aspect, separation of the display controller from the control circuitry is the only manner by which the processing device and/or the memory may be accessed. | 06-09-2011 |
20110185319 | VIRTUAL PIN PAD FOR FUEL PAYMENT SYSTEMS - A method and system for displaying a virtual PIN pad in varying locations on a touch screen in order to prevent fraud or the interception of personal identification numbers. | 07-28-2011 |
20110314552 | Remote Display Tamper Detection Using Data Integrity Operations - Methods and systems for detecting tampering of a remote display. According to one method, a first data integrity result is generated by performing a first data integrity operation on display data to be displayed on the remote display at a secure module. The display data is transmitted from the secure module to the remote display security module. The remote display security module receives the display data. A second data integrity result is generated by performing the first data integrity operation on the display data received at the remote display security module. A determination is made as to whether the remote display has been tampered with at the secure module if the first data integrity result does not match the second data integrity result. | 12-22-2011 |
20120166343 | FUEL DISPENSING PAYMENT SYSTEM FOR SECURE EVALUATION OF CARDHOLDER DATA - A system used in a retail environment for providing end-to-end encryption of payment cardholder data. An input device configured to receive cardholder data is operative to encrypt the cardholder data according to a first encryption method to produce first encrypted cardholder data. A cardholder data handling device is in electronic communication with the input device. A secure evaluation assembly (SEA) is operatively connected to the cardholder data handling device and comprises antitampering control electronics adapted to decrypt the first encrypted cardholder data to produce unencrypted cardholder data. The antitampering control electronics evaluate the unencrypted cardholder data to determine whether the unencrypted cardholder data is payment cardholder data or nonsensitive cardholder data. Finally, if the unencrypted cardholder data is payment cardholder data, the antitampering control electronics of the SEA are adapted to encrypt the unencrypted cardholder data according to a second encryption method to produce second encrypted cardholder data. | 06-28-2012 |
20120286760 | FUEL DISPENSER INPUT DEVICE TAMPER DETECTION ARRANGEMENT - A multi-layer tamper detection arrangement for use with an input device comprising tamper-response electronics and memory. The multi-layer sensor arrangement comprises a flexible circuit assembly configured for connection to the input device. The flexible circuit assembly comprises an outer layer comprising a first tamper-responsive conductor circuit and a first inner layer disposed beneath the outer layer. The first inner layer comprises at least one switch, a removal detection circuit, and a foreign conductor detection circuit. The at least one switch is configured to close the removal detection circuit when the at least one switch is actuated, and the foreign conductor detection circuit is normally open. The first tamper-responsive conductor circuit, the removal detection circuit, and the foreign conductor detection circuit are configured for electrical communication with the tamper-response electronics of the input device. | 11-15-2012 |
20130103190 | FUEL DISPENSER USER INTERFACE SYSTEM ARCHITECTURE - A vending machine user interface can include a first controller operatively connected to an input device capable of receiving payment or account information. The first controller can, with another device, via a second controller, or otherwise, allow secure communication of data from the input device. The first controller, in this regard, can control the communication between the input device and the other device to protect the input device from unwarranted communication from the other device. The first controller can establish a secure channel with the other device using encrypted communications. The first controller, second controller, etc. can be connected to independent printed circuit boards (PCB). Activation of sensors connected to the PCBs can cause the first and/or second controllers to erase data necessary to ascertain/decode communications from the input device, such as encryption/decryption information, or may otherwise decommission the input device or a portion thereof. | 04-25-2013 |
20130103585 | Fueling Environment Wireless Architecture - A method and system for transmitting data between devices within a fueling environment comprising a wireless mesh network wherein the devices are configured to communicate via the wireless mesh network.
