A card exhibiting multiple linear arrays of sensors are provided to detect a presence and movement of an external object (e.g., a read-head of a magnetic stripe reader). Each sensor of each array of sensors may be independently connected to a dual port of a processor so that the processor may determine a direction in which the card is swiped through a magnetic stripe reader. A portion of sensors of each array of sensors may be shared by a portion of inputs and/or outputs of a single port of a processor. Sensors may be cross-coupled to a single processor port so that forward and reverse directions of a card swipe may nevertheless be detected by a single-port processor of a card.

Systems and methods for sensor mechanisms for magnetic cards and devices

Programming fixtures are provided that program devices, such as payment cards, with data, such as personal data, using light transmitters and receivers. A code sequence may be entered into the devices to transition the devices into one of several test modes. Pressing a button may cause diagnostic data to be communicated by the device. Pressing another button may cause default data to be communicated by the device. A personalization test module may capture the diagnostic data and/or default data to document and/or verify operation of the device.

Programming and test modes for powered cards and devices

Dynamic magnetic stripe communications devices are provided as magnetic stripe emulators. A device, such as an application specific integrated circuit, may include a waveform generator that retrieves data from memory and may generate waveforms from the retrieved data to be communicated by the magnetic stripe emulator and received by a magnetic stripe reader.

Systems and methods for waveform generation for dynamic magnetic stripe communications devices

An optical keyboard includes a plurality of photosensors arranged in an X-Y coordinate system where a plurality of rows represent a plurality of X-axes and a plurality of columns represent a plurality of Y-axes. Each sensor represents input to data processing means. When a beam of light is cast onto a photosensor, the photosensor is actuated to transmit a coded signal to a microprocessor board. The microprocessor board scans the array of photosensors row by row sequentially to identify the column position of an actuated photosensor. The input received from the scanning operation is converted to data and transmitted through either a serial or parallel interface to a computer. Interface circuitry converts the data to a form readable by the computer. Thus, by selectively moving a light source to desired photosensors, specific information can be transmitted to a computer for printout or for operation of other devices remotely controlled by the computer to permit the computer to be operated by individuals unable to perform manual keyboard operations.
