First of all, we must be clear that it is a QR code. QR codes are codes that contain information that can be read by a camera, QR codes are two-dimensional, that is, it is necessary for the Xiaomi Redmi 7 camera to read both the width and the height of the QR code and can contain more information than a barcode (one-dimensional).
QR codes are often used to open a web address from a mobile device such as the Xiaomi Redmi 7 using its 12 MP, f/2.2, 1.25µm, PDAF 2 MP, depth sensor camera or if used with a specific application, it can offer information about a product, service or serve to authenticate a user.
In the Redmi 7 you can read or scan QR codes without having to download any application since the code reader is included in the software of the camera.
Estimated time: 2 minutes.
1- First step:
To read or capture a QR code from our Xiaomi Redmi 7 we use the “Camera” app that is included, from the home screen or from the applications menu we look for the icon of a photo camera and open the application.
2- Second step:
From the Xiaomi Redmi 7 camera application, we make sure that we are using the 12 MP, f/2.2, 1.25µm, PDAF 2 MP, depth sensor rear camera and point it at the QR code that we want to read trying to make it appear correctly focused and content within the yellow square or at least within the viewing space , that is, we cannot bring the camera too close to avoid the code being cut off. The QR code must be able to be seen in its entirety on the screen of the Xiaomi Redmi 7, the code does not have up or down, so it does not matter from which angle we approach it.
In the lower right corner of the camera image a QR icon will appear indicating that the Xiaomi Redmi 7 has recognized a valid QR code. Click on that icon to open the available options.
3- Third step:
In the event that the QR code is a web address, the visible address and a button will appear at the bottom of the Xiaomi Redmi 7 screen to open that web address. Click on "Go to the web" to open that web page.
With these simple steps we have learned to read QR codes from our Xiaomi Redmi 7. Most QR codes are used to open websites, either to see the menu of a restaurant or to access a discount code or offer.
If the above methods are not available on your Xiaomi Redmi 7, it may be due to a different version of the operating system (Redmi 7 comes from the factory with the Android 9.0 (Pie); MIUI 9 operating system) or Xiaomi's customization layer (MIUI), you will need to download a specific application to read QR codes. Google Lens is an example of a very useful and versatile app to read QR codes and perform many more functions.
