What does NFC/RFID car key mean?
1 Answers
NFC/RFID car key refers to BMW's digital key that utilizes NFC communication technology, allowing the vehicle to be locked and unlocked via a smartphone without the need for a traditional car key. By bringing the smartphone close to the door handle, the door can be opened. Once inside the vehicle, simply placing the phone on the wireless charging smartphone tray will start the car. NFC stands for Near-Field Communication, which refers to the car's short-range wireless communication technology. RFID stands for Radio-Frequency Identification, also known as an electronic tag. NFC works on the principle of magnetic induction and near-field communication, powering itself through the induction of voltage via radio frequency signals. BMW's NFC provides users with more intuitive information during daily use and allows for simpler and more direct access to content. RFID development is built upon NFC technology, which has gained widespread recognition as it continues to evolve. Currently, NFC technology is not only used for unlocking doors but also for connecting to the car's entertainment system, enabling users to play media content from their phones on the vehicle's touchscreen. The digital NFC key can virtualize the car key into digital form, with its identity issued by the vehicle management authority. The digital key's identity serves as valid proof of mutual authentication between the vehicle and the owner, ensuring the validity, integrity, and security of information and data exchanged between them. By incorporating identity recognition capabilities, the digital key enhances security and convenience.
