Abstract: A payment processing device can implement a monitoring system to detect for tamper attempts at a chip card interface. The monitoring system can establish a baseline when no chip card is present in the chip card interface, or in some embodiments, when it is known that an authentic chip card 14 is present in the slot 21. During subsequent evaluations of the chip card interface by the monitoring system, a response received by the monitoring system that deviates from the baseline can indicate that a tamper attempt at the chip card interface may have occurred. If a tamper attempt is determined by the monitoring system, a remedial or corrective action can be taken.

Abstract: A device may include one or more sources such as circuit elements and electrical components that function as sources for physically unclonable function (PUF) data. PUF data may be acquired from the PUF sources and one or more error correction codes may be applied to the PUF data. The resulting PUF values may be used to generate information that may be used for device security operations such as encryption and tamper detection.

Abstract: A payment terminal can have an integrated memory scanning system that has direct access to the memory of the payment terminal. By having direct access to the memory of the payment terminal, the memory scanning system can access information about the operating system and the applications of the payment terminal to determine if the operating system or applications are performing unauthorized or forbidden actions, which may indicate that a fraudulent transaction or tamper attempt is occurring at the payment terminal. The memory scanning system can determine if an unauthorized action is occurring by comparing the information regarding the operating system or applications obtained from the memory to test criteria stored by the memory scanning system. In addition, the memory scanning system can also have a direct communications with a payment server using information from a network stack in memory that can be accessed directly by the memory scanning system.

Abstract: A device may include a physically unclonable function (PUF) source that has at least one fuse embedded in the device. The PUF source may be responsive to an input for transmitting a signal through the fuse and providing a PUF value based on a measurement of such signal. The device also has circuitry that is configured to modify the fuse by transmitting a signal of sufficiently high current or voltage through the fuse to change its resistance, thereby changing a response of the PUF source to the input.

Abstract: A payment terminal has a clock management unit for providing clock signals to components of the payment terminal. The payment terminal also has a wireless communication interface for communicating wireless signals. A processing unit of the payment terminal may monitor clock signals provided by the clock management unit and determine a phase and frequency difference between a clock signal provided to a component producing RF noise and a clock signal provided to a wireless communication interface of the payment terminal. When RF noise present in the received wireless signal falls below a threshold, the processing unit may sample the received wireless signal.

Abstract: A device may run an application having information with multiple accounts associated with processing of transactions. The application may provide account information that is used to process the transactions. At the same time, a background application may operate on the device. The background application may be compatible with a second device, and when within range of the second device, may communicate background messages relevant to the transaction. The transaction may then be processed based on the account information and the background messages.

Abstract: A comparator can incorporate a hysteresis circuit to control when the output of the comparator changes between a high voltage signal and a low voltage signal. The comparator can receive a differential signal and can output either the high voltage signal or the low voltage signal. When the differential input signal is above a first threshold voltage, the output of the comparator can transition to the high voltage signal and when the differential input signal is below a second threshold voltage, the output of the comparator can transition to the low voltage signal. The hysteresis circuit of the comparator is used to adjust the first threshold voltage and the second threshold voltage required to transition the output of the comparator based on the present state of the output signal of the comparator.

Abstract: A wearable payment device, such as a finger ring worn by a user, communicates payment data to a payment reader that uses the payment data in order to request a payment transaction. Such wearable payment device may be conveniently carried by and accessible to the user such that utilization of the payment device for the payment transaction is less burdensome for the user, thereby encouraging use of the payment device for payments. Indeed, in some cases, such as when the payment device is implemented as a finger ring or other type of jewelry, the user may be encouraged to carry the payment device in an exposed manner such that it is readily available for the payment transaction without the user having to search in a wallet, pocket, or purse.
