US Patent:

6578145, Jun 10, 2003

Filed:

Jun 29, 1999

Appl. No.:

09/342721

Inventors:

John C. Greene - Greensboro NC

Assignee:

Gilbarco Inc. - Greensboro NC

International Classification:

G06F 124

US Classification:

713182, 713150, 713153, 713200, 713201

Abstract:

A system and method for connecting and operating two (2) or more secure keypad devices under the domain of a single processing board is disclosed. The processing board communicates with a security module responsible for host transaction processing. The processing board lies between the keypad and the security module serving both the security module (downstream) and the keypad(s) (upstream). The system permits multiple secure keypads to be used in a manner that is invisible to the security module. A unique message sequence is disclosed among multiple keypads in which only one keypad may be deemed active at a given moment for purposes of passing transaction data through the processing board to the security module. The processing board is responsible for linking each of the keypads together and funneling message traffic among them. A system is disclosed for secure PIN transactions occurring at a single pay point between a plurality of secure keypad devices and a security module configured to communicate with a single secure keypad device.

Filed:

Feb 9, 1998

Appl. No.:

9/020378

Inventors:

John C. Greene - Greensboro NC

Assignee:

Gilbarco Inc. - Greensboro NC

International Classification:

H03M 1100

US Classification:

341 26

Abstract:

A secure keypad device incorporating measures to prohibit electronic eavesdropping. Random interrogation of the rows and/or columns of a keypad matrix is employed to determine which key has been pressed. Implementation of the random interrogation process utilizes the mathematical factorial (!) function in conjunction with an algorithm that derives an interrogation sequence. A random number is generated and fed to an algorithm which will derive an interrogation sequence. The sequence is relayed to a keypad scanner which performs the actual interrogation in order to determine which key has been pressed. Further measures are taken to guard against electronic eavesdropping. For instance, the algorithm is designed to take the same amount of time for an unsuccessful key scan as it does for a successful key scan. Also, the time spent on an unpressed scan line is approximately equal to the time required to record a valid key press.

Assignee:

Marconi Commerce Systems Inc.

International Classification:

H04Q 522

US Classification:

340 101

Abstract:

A system and method to store a sequence of data records relating to attributes of interactions between fuel dispensers and tags. The data records may be stored on the tag or at a location remote from the tag, such as a fuel dispenser, central site controller or other network. The data records may contain the identity of the dispenser, tag and any attribute of a received signal, such as frequency band or signal strength, or other attribute indicative of proximity. Every dispenser that attempts to communicate with a tag in question adds its own interaction data to a limited history of a tag's past interactions with the same and other dispensers. When a dispenser or central site control system examines the contents of the interaction histories, the detected presence of other dispensers or the relative strength of the recorded interaction attributes will determine what, if any, action is to be taken by the dispensers or central site control system to communicate with the tag at issue.

Appl. No.:

9/143006

Inventors:

John C. Greene - Greensboro NC
Howard Weinstein - Greensboro NC

Assignee:

Marconi Commerce Systems Inc. - Greensboro NC

International Classification:

G06K 500

US Classification:

235380

Abstract:

A system for recording a credit or debit transaction on a fuel dispensing apparatus. The system comprises a primary card reader (PCR) for receiving data from a magnetic strip card situated on the exterior housing of the fuel dispensing apparatus and an auxiliary card reader (ACR) for receiving data from a magnetic strip card situated on the exterior housing of the fuel dispensing apparatus. The auxiliary card reader (ACR) is situated such that it is easily accessible to handicapped individuals. Also included is an interface board that accepts input from the primary and auxiliary card readers and determines which of the card readers is currently sending data. Upon determination, the interface board outputs the active card reader data to a card reader in dispenser (CRIND. RTM. ) board coupled to the interface board. The CRIND. RTM.
