About QR Codes
A Quick Response (QR) code is a two-dimensional barcode that can be read easily by smartphones and QR scanners. They are commonly used to store URLs, text information, contact details, or WiFi network configurations.
Best Practices
- Keep the content as short as possible for easier scanning (shorter URLs create simpler patterns).
- Always test your QR code with a scanner app before printing or publishing it.
- Ensure there is high contrast between the QR code (typically black) and the background (typically white).
- Leave an empty "quiet zone" margin around the QR code to help scanners identify it.
