摘要： A system for accepting the input of a PIN comprises a first device receiving a randomized PIN layout derived on a fourth device. The randomized PIN layout is displayed on a display of the first device. A second device comprises an input for accepting a series of key presses to produce a PIN token. The PIN token indicating each of the series of key presses. A third device is in communication with the second device. The third device derives the randomized PIN layout and receives the PIN token from the second device without the PIN token being present on the first device. The third device combines the PIN layout and the PIN token to produce a PIN. The PIN is used to authenticate a transaction. The fourth and third devices each store a shared secret used to independently derive the randomized PIN layout on the fourth and third devices.

摘要： A contactless card reader comprises a contactless card reader front-end coupled to a processor. A communications module is coupled to the processor and a set of sensors is coupled to the processor. The set of sensors determines parameters related to the location, orientation and motion of the card reader. The processor receives the parameters from the set of sensors and utilizes the parameters and scenario configuration data to evaluate a rule. The result of the evaluation of the rule results in a limitation on the operation of the card reader. The communications module is configured to intermittently receive the scenario configuration data from external sources.

摘要： A power management circuitry for a peripheral electronic device includes a power regeneration circuitry, a power selector, a power switch and an audio signal detection circuitry. The power regeneration circuitry receives a continuous periodic sound wave from an audio device and converts the continuous periodic sound wave into an amplified DC electrical signal. The power source selector receives the amplified DC electrical signal and input from a primary power source and provides a power signal output. The audio signal detection circuitry receives the amplified DC electrical signal and transmits a wake-up signal to the power switch circuitry. The power switch circuitry is turned on by the wake-up signal and connects the power source selector to the peripheral electronic device main circuitry and transfers the power signal output to the peripheral electronic device main circuitry.

摘要： A magnetic card reader module includes a magnetic sensor and an adjacent groove, a microcontroller and an application. The magnetic sensor is configured to pick-up an analog magnetic signal generated by swiping a magnetic stripe through the groove. The magnetic stripe is attached to a card and comprises tracks with magnetically encoded data. The microcontroller is configured to convert the analog magnetic signal into a digital signal. The application is configured to analyze the digital signal, and to perform soft-decision decode of the digital signal and to generate an output comprising the magnetically encoded data and side information providing card swipe information feedback.
