How to read QR codes on a XOLO Opus 3?

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 XOLO Opus 3 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 XOLO Opus 3 using its 8 MP| autofocus| dual-LED flash camera or if used with a specific application, it can offer information about a product, service or serve to authenticate a user.
