  • Patent number: 10043177
    Abstract: Methods, devices, and systems are described for sending and receiving messages between a terminal reader and a payment device, such as a credit card. A dynamic signature is calculated on the payment device from an application transaction counter, a terminal unpredictable number, and a transaction amount, and it is sent with an application the locator (AFL) to the reader. The reader then sends a read record command to the payment device to get records associated with the AFL, among other normal processing. While the normal processing is occurring for the transaction, the dynamic signature can be recalculated and compared with that from the payment device in order to assure that nothing has surreptitiously changed the values in the messages.

The mesh includes one or more conductive traces coupled to one or more detectors within the device. The detector can detect an open-circuit or short-circuit condition resulting from an unauthorized attempt to open the housing, and output a signal to trigger an appropriate countermeasure. The electrical contacts along the trace that are monitored can be selected differently from one manufactured unit to the next, and can be selected based on a randomness function. The selection of contacts may be made during or after manufacturing of the device. The mesh can include multiple metal traces that run very close together, in parallel, across one or more interior surfaces of the housing, allowing detection of both open-circuit and short-circuit conditions.

  • Patent number: 8925814
    Abstract: A target is read in the presence of interference light. A photodetector generates an output signal composed of an information signal and an interference light signal. A rangefinder determines the distance of the target in a range of working distances. A controller adjusts a scan angle of a scan drive to a narrow value and adjusts an output power of a laser diode to a low power level when the target is determined to be far out in the range. The controller adjusts the scan angle to a wide value and adjusts the output power to a high power level when the target is determined to be close in the range. Signal processing circuitry processes the output signal with the information signal having a greater magnitude than that of the interference signal due to the high power level to mitigate the presence of the interference light. A power safety arrangement including dual power monitors checks the output power of the laser beam.

  • Publication number: 20130126613
    Abstract: A system and a method for testing a magnetic stripe decoding chip are provided. The system includes a host, a digital-to-analog converter, and a testing device. The host outputs simulation signal data. The digital-to-analog converter receives the simulation signal data and generates a test waveform signal representing a test string. The testing device includes a signal input terminal, a signal conversion circuit, a chip slot, and a processor. The terminal receives the test waveform signal. The chip slot is configured to receive a decoding chip. The circuit includes a transformer connected between the terminal and the chip slot, and is configured to couple the test waveform signal into a pseudo track signal. The processor receives a decoded string generated after decoding the pseudo track signal by the decoding chip. Through comparing the decoded string with the test string, a decoding function of the decoding chip can be determined.

  • Publication number: 20130020391
    Abstract: An automated system for reading optical codes includes a conveyor system to automatically transport objects and an object measurement system positioned along the conveyor system to measure the transported objects. In one configuration, the object measurement system generates model data representing three-dimensional models of the objects; multiple image capture devices positioned along the conveyor system capture images as the objects are transported to enable an optical code reading system to read optical codes that are captured in the images. An exception identification system associates optical codes with the three-dimensional models to determine whether an exception has occurred.
