A restaurant menu or event link should not require typing a long web address. On iPhone, point the camera at the whole QR code and tap the detected link. Pixel phones can do the same with camera scan suggestions enabled, or use their QR scanner in Quick Settings. Other Android models vary.

This ranks above a display adjustment for the small tasks it removes when you are out and about. Keep the code well lit and hold the phone steady. Treat the destination like any other link: check the website before entering information. The illustration is a symbol, not a scannable code.
