About This Tool

A QR code (Quick Response code) is a 2D barcode that can store text, URLs, contact info, Wi-Fi credentials, and more. Smartphones can scan QR codes with their cameras, making them ideal for bridging physical and digital worlds.

When to Use

  • Adding a URL to print materials (business cards, posters, menus).
  • Encoding Wi-Fi credentials (SSID and password) for easy guest access.
  • Linking to app stores, payment pages, or contact vCards without typing.

Common Mistakes to Avoid

  • Making QR codes too small to scan reliably — minimum 2.5cm × 2.5cm for print.
  • Using very light foreground / very dark background — scanners need contrast.

Frequently Asked Questions

Q. How much data can a QR code store?A. Up to 4,296 alphanumeric characters. URLs should be kept short for better scannability.
Q. What is error correction?A. QR codes have built-in redundancy (Level M = 15% recovery). Even if part of the code is damaged, it can still be scanned.
