Now the technology should be able to unlock the car with mobile phone NFC, right?

The car key function of mobile phone is to replace the car key with mobile phone, which can easily open the car door, start the car or lock the car. The mobile phone can continue to be used as a car key within 24 hours after the low battery is automatically turned off. Car keys can be shared at any time and cancelled at any time. It is stored in a security chip and cannot be stolen and copied.

At present, Huawei, Apple and other mobile phone manufacturers have released the function of using mobile phones as car keys. Take Huawei as an example. When Huawei released P30 last year, it released the key function of mobile phone car. At present, this function has supported many models.

The car key function of Huawei mobile phone is based on NFC function. Even if the phone is not unlocked or has no power, the car key function can still be used. At present, Huawei mobile phones have supported some models of BMW 3 Series X5, X7 and BYD. In line with the 3C specification of the Global Automobile Federation. Huawei is also gradually cooperating with more car companies.

At present, Huawei mobile phone supports the car key function: Huawei P30 Pro limited edition set (full netcom version with 8gb+5 12gb). Huawei P30 Pro (standard full netcom 8gb+ 128gb, top full netcom 8gb+5 12gb, standard mobile customized version 8gb+ 128gb, limited set full netcom top 8gb+5 12gb, advanced mobile customized version)

How to use the car key function of Huawei mobile phone;

If the mobile phone is accidentally lost, you can cancel the car key in the car factory APP, car machine or website. You can also share multiple keys with others in the car factory APP on your mobile phone.

Yes, but it is related to many factors.

First: the mobile phone needs to support NFC. This is currently more, iphone X, Huawei mate 30, Xiaomi 9 5G and so on. I have never used Samsung i9 100 used by the landlord. The information on the Internet is that this version is only available in Korea and Japan, and the international version 9 100 does not have NFC.

Second: cars need to support NFC. At present, the models I know that support NFC unlocking are: Tesla model 3;; ; Tucki P7; Song Qin, wait. On June 20 19, Xiaomi announced that he had reached a strategic cooperation with Xpeng Motors P7 to unlock the vehicle through NFC.

Third: mobile phone and vehicle authorization. Authorization here does not refer to the mobile phone model and vehicle authorization, but refers to the user's mobile phone and vehicle authorization. Because nfc has its own protocol, it must conform to the prescribed protocol to communicate. Moreover, when a general vehicle supports NFC, it must have been tested with many mobile phones on the market, so it is basically compatible with all mobile phones. However, if you want to use your own mobile phone to drive a vehicle, you need to bind your mobile phone to your own vehicle and unlock it with a key. NFC rights can also be temporarily granted to others according to time periods and other conditions. When the time is up, you can't use other mobile phones to drive the vehicle.

No physical key is the future development direction, and NFC keyless startup of mobile phones will be used more and more.

At present, the application of NFC mainly lies in encrypted contactless applications, such as access cards in some residential areas and office buildings, so the use is limited, such as bus cards. For applications with high security level, NFC of mobile phones can't be managed, unless mobile phone manufacturers support common protocols at the bottom, such as using NFC to swipe mobile phones, and only soft plaintext information such as card number is transmitted in industry protocols. From the application point of view, NFC still has some limitations, such as relying on mobile phone support, relying on the support of application operators, unlocking or starting the vehicle you ask. In terms of maintenance and security, I think the car factory is considering more secure identity verification and authentication mechanisms, such as faces and fingerprints. Keys actually have a layer of value concept, which can be keyless face or fingerprint entry and keyless contactless start.

I use Bluetooth to drive directly. Nfc probably means unlocking a car. I haven't heard of any research so far.
