Patent number: 6817534Abstract: A smart card, having a set of standardized contact pads and an additional set of contact pads to provide additional performance characteristics. The additional contact pads are formed on the smart card on the area located between the ISO 7816 standardized contact pads C1 through C4 and C5 through C8, which area was previously used solely as a ground plane connection to contact pad C5. By increasing the number of contact pads, the additional pads can be used for input/output connections, memory, flash memory and/or interfaces with specific functions such as a service provided interface.Type: GrantFiled: April 7, 2003Date of Patent: November 16, 2004Assignee: Litronic, Inc.Inventor: Robert J. Gray

Patent number: 6557754Abstract: One aspect of the present invention is a method and apparatus of providing a card and/or reader that recognizes a communication mode of a corresponding reader and/or card. The card reader comprises a memory and a card interface circuit to detect a mode of a card. A processor coupled to the card interface circuit and the memory, communicates with the card in the detected mode if the detected mode matches a communication mode of the processor. The card comprises a memory and a reader interface circuit to detect a mode of a reader. A processor coupled to the reader interface circuit and the memory, communicates with the reader in the detected mode if the detected mode matches a communication mode of the processor. Another aspect of the present invention is a method and apparatus of providing a card and/or reader that is operable in two communication modes.Type: GrantFiled: December 1, 2000Date of Patent: May 6, 2003Assignee: Litronic, Inc.Inventors: Robert J. Gray, Lee Gudmundsen, Charles E. Frasier

Patent number: 6087955Abstract: A method and apparatus for controlling access to at least one program on a computer by verifying data entered through a keyboard with data stored on a token such as a card, while isolating the entered data from the computer. The apparatus includes a verification device, external to the computer, which receives the card. When activated, the verification device isolates itself from the computer, and then receives the entered data and forwards the entered data to the card. The card compares the entered data with data stored on the card. The result of the comparison is forwarded to the verification unit which generates a status signal indicative of the result of the comparison. The verification device is operable in a first mode wherein data provided to the verification unit via the keyboard is not provided to the computer.Type: GrantFiled: July 29, 1998Date of Patent: July 11, 2000Assignee: Litronic, Inc.Inventor: Robert J.

Patent number: 5844497Abstract: A method and apparatus for controlling access to at least one program on a computer by verifying data entered through a keyboard with data stored on a token such as a card, while isolating the entered data from the computer. The apparatus includes a verification device, external to the computer, which receives the card and a connector. When activated, the verification device isolates itself from the computer, and then receives the entered data and compared it with data stored on the card. The verification unit then generates a status signal indicative of the result of the comparison. The verification device is operable in a first mode wherein data provided to the verification unit via the keyboard is not provided to the computer. The verification device is also operable in a second mode, wherein at least one program on the computer is accessible via the keyboard when the data from the keyboard matches the data from the card.Type: GrantFiled: November 7, 1996Date of Patent: December 1, 1998Assignee: Litronic, Inc.Inventor: Robert J.
