The NFC reader includes the main MCU, NFC chip, and is connected to the private CAN of the Bluetooth module. NFC communication authentication needs to be run through the ESE in the Bluetooth module. The recommended locations for the external card reader VLG are the B-pillar trim, the exterior mirror, and integrated with the door handle module. The static current of the external card reader is less than 0.5mA.
NFC operating frequency 13.56MHz, Maximum recognition distance Up to 40 mm Support ISO/IEC 14443 Type read/write mode, support FOTA function, allowing the master node to wirelessly upgrade the NFC Reader firmware.
