Near Field Communication (NFC) is a short-range two-way communication technology that allows two devices to communicate within a few centimeters of distance and has a maximum data transfer rate of 424 kb / s for secure, simple data between two devices. exchange. As a branch of RFID technology, NFC is expected to expand from mobile phones to automotive applications. NFC is seen as the implementation technology for many new in-vehicle features and simplifies the use and operation of existing in-vehicle features.
When the user's mobile phone is connected to the car for the first time, Bluetooth pairing requires multiple user interactions, and NFC only needs a "tap & pair" quick pairing interaction. Just point the NFC phone to the NFC device in the dashboard, tap the phone screen, and confirm the pairing. The car will activate the car Bluetooth interface and pass the internal Bluetooth address, PIN code, device name and other information to the NFC phone. Then, the mobile phone establishes a secure link with the car through the Bluetooth interface and completes the device pairing process. This intuitive pairing process is usually completed in 1-2 seconds.
Drivers can use NFC to set up a personalized interior environment, such as setting up air conditioning, infotainment systems (sound and display settings), lighting, final destinations, and more. Personalization is not limited to drivers, and passengers can also use the personalization feature. Personalization information is stored in the NFC tag, and you can activate the desired personalization by simply swiping the personalized tag on the dashboard with the NFC reader. Other use cases include user authentication, electronic payment, and activation services, for example, activation of other navigation maps.
Low power requirements also make NFC technology suitable for key cards. The owner can use the NFC device to open the door lock, save the user's seat position, radio channel settings, etc., or use the NFC phone or NFC tag to lock or unlock. NFC makes data sharing between cars and mobile phones easier. NFC is also ideal for solutions that require flexible use of cars, such as shared cars, car rental, social sharing, fleet management and more.
The NFC interface is easy to carry and can also be used outside the car. When the user locks the car, the car will send the car status information such as the car lock status, car position, fuel quantity, etc. to the mobile phone, which is convenient for the user to use. All of these use cases show that NFC technology has great potential for application in automobiles. Some use cases require NFC-based devices (eg, cell phones, PDAs, etc.), while others rely on NFC/RFID public infrastructure (eg, taking public transportation, paying, purchasing tickets, etc.). Therefore, the application prospects of automotive NFC are directly dependent on the future market penetration of NFC equipment and the changes in NFC/RFID infrastructure around the world.
