What is a QR Code and how does it work?
A QR Code (Quick Response Code) is a two-dimensional matrix barcode designed to store information readable by smartphones and optical scanners. Originally created for the automotive industry, QR codes are now used globally to share website links, digital menus, Wi-Fi access, vCard contact information, and payment methods.
Best practices for scannable QR codes
- High contrast: Ensure high contrast between the QR code pattern and background color. Dark patterns over light backgrounds work best.
- Proper sizing: If you plan to print your QR code, choose high resolutions (512px or 1024px) to avoid pixelation during mobile scanning.
- Short URLs: Shorter text or URLs generate simpler matrix patterns, making them significantly faster to scan.
