  • Patent number: 11295319
    Abstract: 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 the 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.

  • Patent number: 8915434
    Abstract: A card reader guide for use in a fascia of a self-service terminal is described. The card reader guide defines a card reader aperture extending in a first direction through which a customer may insert a data card. The card reader guide also comprises: a first protrusion extending (i) along part of the card reader aperture through which a magnetic stripe of the card passes, and (ii) towards the customer, wherein the first protrusion defines a stripe path in registration with the magnetic stripe of the card as the card is inserted by the customer; a second protrusion, opposite to, and aligned with, the first protrusion, and extending (i) along the part of the card reader aperture through which the magnetic stripe of the card passes, and (ii) towards the customer; and a magnetic reader detector located in the first protrusion at the stripe path.

  • Patent number: 8704633
    Abstract: A method of preventing fraud at a self-service terminal is described. The method comprises: receiving a signal from an electromagnetic sensor located in the vicinity of an electromagnetic signal transmitter; monitoring a drive signal being delivered to the electromagnetic signal transmitter; and comparing the drive signal with the electromagnetic sensor signal. The method then ascertains if a state of the electromagnetic sensor signal is inconsistent with a state of the drive signal; and triggers an alarm when the state of the electromagnetic sensor signal is inconsistent with a state of the drive signal.

  • Patent number: 7469350
    Abstract: A particular problem for self-service devices incorporating USB devices (12) and a USB host (14) is that, when communication is lost between the USB host and one or more of the devices it is difficult (in particular situations) to reset those USB devices without manual intervention. We address that problem by using self-powered USB devices and/or bus powered devices connected to USB hubs, and by creating a power control interface (18) which is itself a USB device. That power control interface takes instructions from the USB host and is able to interrupt a power supply (20) to the USB devices to provoke automatic reset of those devices. Additionally, a watchdog application within the power control interface causes reset of that interface should it malfunction. Also, a master watchdog application at the USB host communicates with a slave watchdog application at the power control interface via a USB link.
