Scan QR Codes: The primary function of the app is to scan and decode QR codes. Users can simply point their device's camera at a QR code, and the app will quickly recognize and interpret the encoded data.
Scan Barcodes: In addition to QR codes, the app can also scan various types of barcodes, such as UPC (Universal Product Code), EAN (European Article Number), ISBN (International Standard Book Number), etc. These barcodes are commonly found on product packaging and can be scanned to obtain product information.
Decoding Data: Once a QR code or barcode is scanned, the app decodes the information stored in the code. For example, a QR code might contain a URL, text, contact information, a Wi-Fi network's credentials, etc. The app extracts and presents this information in a user-friendly format.
History and Favorites: The app often maintains a history of scanned QR codes and barcodes, allowing users to revisit previously scanned codes. Some apps also provide the ability to mark certain scans as favorites for easy access.
Generate QR Codes: Some scanner apps offer the ability to generate QR codes. Users can input text, URLs, or other data, and the app will create a QR code that encodes that information. This feature is useful for sharing contact information, website links, and other data.
Flashlight Control: To ensure efficient scanning even in low-light conditions, many apps provide a flashlight control option, allowing users to enable or disable the device's flashlight during scanning.
Auto-Focus and Detection: The app typically includes auto-focus and real-time detection capabilities to help users accurately scan QR codes and barcodes quickly and effortlessly.
Privacy and Security: Good scanner apps prioritize user privacy and data security. They do not collect unnecessary user data and provide options to delete scan history or disable analytics.
