Publication number: 20230029723Abstract: A card reader's motorized transport is controlled by firmware of the reader so as to control a distance that any card can be pulled into the reader during a transaction on a host device. The distance is sufficient enough to allow an embedded chip on the card to be read by a chip read interface but is insufficient to be read by a magnetic read interface. Furthermore, the entire length of the card is prevented from completely passing over the magnetic read interface during the transaction such that any skimmer placed within the reader is physically unable to read the magnetic card information from the magnetic strip of the card. In an embodiment, the firmware is configured to permit only chips from the cards to be read for transactions or configured to turn off chip only reading by permitting both chip reads and magnetic strip reads for each transaction.Type: ApplicationFiled: October 14, 2022Publication date: February 2, 2023Inventor: Graeme Mitchell

Patent number: 11562377Abstract: A system and method is described for detecting a foreign object such as a skimmer placed adjacent to a bezel for a magnetic card reader device, as used in automatic teller machines and gas pumps. At least two sensors are mounted adjacent to the bezel. Each sensor provides a signal that varies when a skimmer is mounted adjacent to the bezel. A controller receive measurement signals from the sensors, and generates an alarm signal when the measurement signals differ from associated predetermined baseline signals by at least associated predetermined thresholds. The alarm signal indicates that a foreign object has been detected adjacent he bezel. The sensors may be capacitive, time of flight, spectral, radar, and/or inductive. The capacitive sensors may include three or more plates, forming multiple capacitive pairs, each capacitive pair effectively forming a separate sensor.Type: GrantFiled: December 2, 2021Date of Patent: January 24, 2023Assignee: NCR CorporationInventors: Graeme Mitchell, Francesc Alier Pous, Martin Barrett, Kevan Johnston, Peter Vettraino

Patent number: 10681036Abstract: Various embodiments include composite security interconnect devices and methods. One method embodiment that may be performed by a composite security interconnect device, also referred to herein as a security controller, includes decrypting a first encrypted input received from a peripheral device with a first encryption key to obtain clear text. The first encryption key may be an encryption key established between the security controller and the peripheral device. The method further includes encrypting the clear text with a second encryption key to obtain second encrypted input, the second encryption key being a key of an encryption key pair established with a transaction processing host.Type: GrantFiled: March 28, 2014Date of Patent: June 9, 2020Assignee: NCR CorporationInventors: Kevin Horgan, Gordon Chisholm, Graeme Mitchell, Alexander William Whytock, David Sleeman, Colin Sinclair
