Xiaomi Redmi 7 Scanner: How to Enable, Configure and Scan QR-codes, documents and barcodes

Introduction: why you need a scanner on a smartphone and what it can do

Modern smartphones have long ceased to be just a means of communication — they have become universal assistants in life, work and even finance. Xiaomi Redmi 7, despite the budget position, is equipped with a built-in scanner that allows you to read QR-Codes, barcodes, even text from documents without installing third-party apps, which saves time by pointing the camera at the code to instantly open a link, add a contact, or pay the bill.
