1, the nfc/rfid car key is a bmw digital key using nfc communication technology, which allows the owner to unlock and lock the vehicle through the smartphone in hand, without the need to carry a traditional car key. So what is nfc? It is the car's near field wireless communication technology, and rfid is short for radio frequency identification, also known as electronic tags. Each vehicle has unique nfc near field communicationPassword, which can be tied to a smartphone.
2, NFC/RFID car key is a car key based on NFC (near-field-communication, Near Field wireless Communication technology) and RFID (radio-frequency Identification, Radio Frequency identification technology). It uses a smartphone as a digital key to lock and unlock the vehicle through NFC communication technology, without the use of traditional physical keys.
3. NFC (Near Field Communication (short distance wireless communication technology), RFID (Radio Frequency Identification), also known as electronic tags. NFC/RFID car keys use these technologies to allow owners to unlock and lock their vehicles via their smartphones, eliminating the need for traditional keys. 4, in automotive technology, nfc/rfid car key is an innovative digital solution, it uses nfc communication technology, completely subvert the use of traditional car keys. With a smartphone, noneA physical key is required to unlock the vehicle with just one touch. Once inside the car, simply place your smartphone on a pre-set wireless charging tray and the vehicle automatically starts, bringing unprecedented convenience to the driving experience.
5, bmw nfc/rfid car key is a BMW digital key using nfc communication technology, the vehicle can be locked and unlocked through a smartphone, without the use of traditional car keys. You can open the door by holding the smartphone to the door handle, and once inside the car, you can put the phone on the wireless charging smartphone trayStart the vehicle.
6, NFC refers to Near Field Communication, that is, the vehicle "near field wireless communication technology"; RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification, commonly known as electronic tags.
In summary, Magsafe charging case and wireless charging case are in functionThere are obvious differences in technical characteristics, design and appearance. The Magsafe charging case is designed for devices that support magnetic technology for higher compatibility and charging efficiency; The wireless charging box has a wide range of applications and strong versatility. According to the needs of individuals and the characteristics of the device, you can choose a suitable charging box to meet the needs of daily use.
Magnetic device is different: Simply put, the difference between the magsafe charging box and the wireless charging box is that the magsafe charging box has more than a circle of magnetic device inside the wireless charging box, which can be adsorbed in the magsafe On the charger. In addition to supporting wireless charging and lightning interface charging, the magsafe charging case also supports magsafe charger charging. Different serial numbers: The last four digits of the serial numbers are different.
The magsafe charging case has an extra magnetic device inside the wireless charging case, which can be attached to the magsafe charger. In addition to supporting wireless charging and lightning interface charging, the magsafe charging case also supports magsafe charger charging. The magsafe charger is the wireless charging technology introduced by the iPhone company, and magsafe is kept inWireless charging will be included in the specifications of the new generation of products.
2. At the beginning of the redesign, the radiation problem was considered, and its radiation was negligible; On the contrary, you need to worry about some daily appliances such as microwave ovens (the maximum radiation under the door after starting), induction stoves, desktop computers (the side and back radiation is larger), and laptop computers (the keyboard radiation is larger), which are more radiation in the working state than wireless routers.
3, wireless power supply technology once the wireless power supply technology is commercially available, it will be particularly convenient, just like our daily use of WIFI. With WiFAfter i, we no longer have to worry about the loss of traffic, anytime, anywhere to use the wireless network to watch video. And this technology, led by the United States, they are using non-radioactive wireless energy to charge, is a very applicable cutting-edge technology.
4, so the wireless power supply technology is still relatively far away from us. But wireless charging technology is really widespread. At present, automobile manufacturers such as Audi, BMW, Mercedes-Benz, Volvo, Toyota, etc., and communication companies such as Qualcomm have begun to study wireless charging technology for electric vehicles.
5, if the middle is goldIt is a railing, and the railing is charged, so it is really difficult to understand the wireless transmission of electricity. At most, it can transmit frequency, not energy. The power supply of the future is bound to be wireless and non-inductive. Thirty years ago, someone told you that wifi Internet access, you will think that this person is crazy, wireless power supply as a new technology, commercial prospects have been initially revealed, and future development is unlimited.
6, refers to the non-physical contact power transmission mode, is the third wireless revolution after wireless communication, wireless network, is regarded as a basic application of the industry as a cutting-edge technology, cross-product applicationA wide range, is expected to promote the national and even the world communications, electronics, Internet of things, new energy and other industries breakthrough and innovation, by the Massachusetts Institute of Technology scientists are developing a new power supply technology, the project began in June 2007.
