1. What Is a QR Code?
A QR code (Quick Response code) is a digital barcode that stores information like a website link or app download page.
When your phone scans it, the camera instantly recognizes the code and redirects you to the related page — usually the App Store or Google Play Store.
Companies, developers, and advertisers use QR codes to help people download apps quickly without searching manually or typing names.
