The HUF13145 Door Handle with NFC is designed to enable users of a car with a passive entry system to lock and unlock the doors using a key fob or an authorized NFC device. When an NFC device approaches the NFC antenna on the door handle, a signal is sent to the electronic control unit (ECU) to initiate the authorization sequence for unlocking or locking the door. The door handle communicates with the ECU using a one-wire interface and with the NFC device using Near Field Communication. The NFC communication between the door handle and the NFC device occurs at a proximity range of up to 2cm. The door handle is equipped with an NFC reader that follows the ISO 14443-A standard and uses a PCB loop antenna. The NFC frequency rate is 13.56 MHz ± 7 kHz, and the data rate is 106 kb/s. The door handle also complies with regulatory requirements, such as FCC and Industry Canada standards, to ensure proper operation and minimize interference. The product label with radio certification marks and other relevant information can be found on the back side of the NFC module of the door handle.
