Abstract:
A system for near field communication (NFC) and frequency modulation (FM) communication includes a NFC microchip, a FM microchip, a control microchip, a switch module. The switch module switches between the NFC matching module and the FM matching module under control of the control microchip. A NFC matching module electronically connected to the antenna modulates working frequency of the NFC microchip to match with an antenna. A FM matching module electronically connected to the antenna modulates working frequency of the FM microchip to match with the antenna.
