Where is the NFC sensing area of Huawei mate8?

The nfc sensing area of Huawei mate8 is at the top position directly above the rear camera. In all NFC usage scenarios, it is effective to identify this location.

NFC translated into Chinese is called short-range wireless communication technology, which was jointly developed by Philips, Sony and Nokia. This function evolved from the earliest contactless radio frequency identification, which can exchange information within a few centimeters. Nowadays, with the development of science and technology, NFC functions have spread all over people's lives.

NFC itself has three different modes, namely, read-write mode, peer-to-peer mode and card mode. Through these three modes, the NFC function of mobile phones can help people realize common needs such as credit card payment and data transmission.

NFC function can be used to complete data transmission between two devices, and the overall way is similar to Bluetooth function. But in reality, NFC is not as fast as Bluetooth and WiFi, so it is rarely used by people. Point-to-point mode used by this function.

4. Other extended functions, such as access cards.

In the latest Xiaomi MIUI system, the mobile phone supports adding access cards, and it is very convenient to use the mobile phone to brush the access control after adding.
