Testing QR Code Scanning in Mobile Applications

Overview

QR Code Scanning Testing ensures that mobile applications accurately detect, read, and process QR codes using the device camera under real world conditions. By validating scanning behavior on real devices, teams can assess camera access, focus handling, lighting tolerance, and response time across different devices and OS versions. This helps ensure reliable QR recognition, correct data parsing, and a smooth user experience in scenarios such as payments, authentication, onboarding, and app navigation.
