A near field communication (NFC) device includes a phase detector for receiving a reference clock signal, detecting a phase of the reference clock signal, outputting a generated clock signal having a frequency synchronized with the reference clock signal, and storing phase information of the generated clock signal as a first digital code. A phase delay calculator compares the phase of the generated clock signal applied from the phase detector and a reference phase to calculate a delta value while performing an active load modulation (ALM) operation and stores the delta value as a second digital code. A transmission clock signal generator reflects phase information stored as the first digital code and the second digital code to output a transmission clock signal. Accordingly, the NFC device controls the phase of the transmission clock signal applied to the antenna of the reader device to have optimal load modulation amplitude (LMA).

Power is transmitted to an implanted receiving coil oriented such that an axis of the receiving coil is parallel to skin of a subject. A transmitting coil is in a housing, which is placed against the skin. A central axis of the transmitting coil is perpendicular to the skin. A portion of the transmitting coil is over the receiving coil. A first distance, from the axis of the transmitting coil to a center of the receiving coil, is greater than a second distance, from the axis of the transmitting coil to an inner edge of the portion of the transmitting coil. The first distance is less than a third distance, from the axis of the transmitting coil to an outer edge of the portion of the transmitting coil. Circuitry powers the implant by driving current through the transmitting coil that induces current in the receiving coil.

Provided is an electronic device that increases operability when writing information (for example, unique user information) that allows writing to a wireless tag from the outside. The electronic device of the present disclosure includes a storage device that stores first registered information; a wireless tag that stores second registered information; and a system-control unit that updates contents of the second registered information based on the first registered information; wherein the system-control unit updates contents of information other than information that allows writing when there is writing to the wireless tag from the outside.

A position alignment system facilitates positioning of a contactless card in a ‘sweet spot’ in a target volume relative to a contactless card reading device. Alignment logic uses information captured from available imaging devices such as infrared proximity detectors, cameras, infrared sensors, dot projectors, and the like to guide the card to a target location. The captured image information is processed to identify a card position, trajectory and predicted location using one or both of a machine learning model and/or a Simultaneous Localization and Mapping logic. Trajectory adjustment and prompt identification may be intelligently controlled and customized using machine-learning techniques to customize guidance based on the preference and/or historical behavior of the user. As a result, the speed and accuracy of contactless card alignment is improved and received NFC signal strength is maximized, thereby reducing the occurrence of dropped transactions.
