Near Field Communication and Wireless Charging Device and Switching Method Using The Same

摘要

A near field communication and wireless charging device includes a coil, a tuning module, a near field communication module, a wireless charging module, and a power storage device. The coil is configured to receive electromagnetic waves. The tuning module is electrically connected to the coil. The near field communication module includes an attenuator and a near field communication control circuit. The attenuator is configured to attenuate the energy of electromagnetic waves transmitted from the tuning module. The near field communication control circuit is electrically connected to the attenuator. The power storage device is electrically connected to the wireless charging module. Electromagnetic waves are magnetically coupling to the coil, and the coil transmits signals of the electromagnetic waves to the near field communication module through the tuning module, or transmits the energy of the electromagnetic waves to the power storage device through the tuning module and the wireless charging module.
