Have you ever had the experience of sticking your phone on ** when you want to pay with your mobile phone, but you don't know how to stick your phone on **? Or when you want to open the door with your phone, but find that your phone doesn't recognize the access card? The root of these problems is that you don't know where your phone's NFC zone is.
The NFC sensing area refers to the part of the phone that can communicate in the near field, usually on the back of the phone, near the camera or logo. NFC is a short-range high-frequency wireless communication technology, and devices (such as mobile phones) using NFC technology can exchange data in close proximity to each other, such as mobile payment, electronic ticketing, access control, mobile identity recognition and other applications. NFC evolved from the integration of contactless radio frequency identification (RFID) and interconnect technologies.
Different mobile phone brands and models may have different locations of NFC sensing areas, you can determine the specific location of your mobile phone's NFC sensing area by checking the manual or official website of your mobile phone.
For example, the NFC sensing area on the iPhone is at the top of the logo on the back of the phone, near the right side of the camera. The NFC sensing area of the Xiaomi Mi 11 phone is under the camera on the back of the phone.
So, how to find your phone's NFC sensing area? There is a simple way to use a card with an NFC chip (such as a bus card, access card, etc.) to slowly slide on the back of the phone until you hear a prompt sound or vibration from the phone, which means that you have found the location of the NFC sensing area. You can also wrap the card in a piece of paper so that you don't scratch the back of your phone.
