  • Patent number: 9967038
    Abstract: Techniques are described for data transfer in spin-based systems where digital bit values are represented by magnetization states of magnetoresistive devices rather than voltages or currents. For data transmission, a spin-based signal is converted to an optical signal and transmitted via an optical transport. For data reception, the optical signal is received via the optical transport and converted back to a spin-based signal. Such data transfer may not require an intervening conversion of the spin-based signal to charge-based signal that relies on voltages or currents to represent digital bit values. In addition, techniques are described to use magnetoresistive devices to control the amount of current or voltage that is delivered, where the magnetization state of the magnetoresistive device is set by an optical signal.

    Abstract: An electro-optical code reading terminal for dynamically switching mode of operation from a printed code reading mode to an electronically displayed code reading mode is provided. The electro-optical code reading terminal measures and monitors, using one or more magnetic sensors, a magnetic field experienced at the electro-optical code reading terminal. When the electro-optical code reading terminal device determines that a change in the measured magnetic field exceeds a predetermined threshold within a predetermined time period, the electro-optical code reading terminal device infers presence of an electronically displayed code. The electro-optical code reading terminal device then switches its mode of operation from the printed code reading mode of operation to the electronically displayed code reading mode of operation.

    Abstract: Some battery-powered devices, such as smartphones, can be unlocked with use of wearable NFC (Near Field Communication) authentication devices. However, using conventional NFC authentication procedures is expensive in terms of power consumption because of continual rediscovery and reauthentication of the wearable authentication device. To address this, the present inventors, devised, among other things, more efficient methods for authenticating NFC-tagged authentication device, such as rings. For example, one embodiment uses two NFC polling loops or structures, instead of one as conventionally done. The first loop, used for initial authentication, entails scanning for two or more types of NFC tags. And the second loop, invoked after initial authentication, scans for a smaller subset of the two or more types to conserve battery power.

    Abstract: Skimming modules can be attached at self-service terminals, such as an automated teller machine or account statement printer, by manipulation with fraudulent intent by third parties who attempt to read the data from a magnetic stripe card introduced into the card reader (10). In order to counteract this problem effectively, a protective device (26, 28) is proposed that contains a protective generator (26) and an inductor (28) operatively connected thereto to generate an electromagnetic protective field (29) that is suitable for compromising the function of the spying device (SM), wherein the protective device (26, 28) generates an electromagnetic protective field (29) with a protective signal that simulates the type of signal that occurs when magnetic stripe cards are read. Through the protective field a special protective signal is induced in the potentially present skimming module to imitate the reading of the magnetic stripe card.

    Abstract: A system for tracking RFID tags with a reader device having a plurality of antennas. The antennas are positioned such that portions of at least two of the plurality of antennas physically overlap each other and are in approximately the same plane. A pair of overlapping antennas are also positioned so that an RFID tag is positioned within both signal fields of the pair of overlapping antennas. In addition, the reader device is configured to selectively activate the plurality of overlapping antennas to thereby selectively interrogate one or more of the RFID tags, and the reader device is configured to use the selective interrogation of the one or more RFID tags to track the locations of the RFID tags.

  • Patent number: 7721963
    Abstract: The invention describes a device for a self-service terminal which contains a card reading device, for preventing the possibility of data on a card which is to be read by the card reading device 10 being spied-out by means of a spying-out apparatus which is installed in the vicinity of the card reading device 10. The device comprises a protection apparatus 26 for generating a protective electromagnetic field which is suitable for impairing the functioning of the spying-out apparatus. The protection apparatus is controlled by a control unit 24 of the card reading device, which control unit also controls a card transportation apparatus 18 and/or a reading apparatus 20, 22 of the card reading device, such that the protective field is changed during reading of the card in the card reading device 10 such that it is ensured that reading of the card in the card reading device 10 is not impaired.
