摘要： Disclosed is a near-field communication (NFC) system that includes an NFC supporting apparatus. The NFC supporting apparatus includes a dual coil and a first switch. The dual coil includes an NFC band coil and a radio frequency (RF) band coil. An RF amplitude modulation signal is generated at the RF band coil in response to a transmission from an implantable device. The first switch is configured to switch the NFC band coil based on the RF amplitude modulation signal. The NFC band coil is configured to generate an NFC amplitude modulation signal at an NFC band coil of an NFC reader in response to the first switch.
