QR Code Generation: Structure, Standards, and Best Practices
Key Takeaways
- QR codes can store up to 4,296 alphanumeric characters with built-in error correction that allows scanning even when partially damaged.
- QR codes support multiple data types: URLs, text, WiFi credentials, vCards, calendar events, and more.
- All QR code generation happens in your browser — your data is never sent to any external server.
QR (Quick Response) codes have evolved from their origins in Japanese automotive manufacturing to become a universal bridge between physical and digital worlds. From restaurant menus and payment systems to event tickets and product packaging, QR codes enable instant information access with a smartphone camera scan. Understanding QR code best practices ensures your codes are scannable, secure, and effective.
Global QR code usage increased by over 400% between 2020 and 2024, driven by contactless interactions.
Growth Trend
Common Use Cases
URL Sharing
Encode website URLs for print materials, business cards, and signage — allowing instant access without typing long web addresses.
Contact Information (vCard)
Encode name, phone, email, and address in vCard format so contacts can be saved to a phone with a single scan.
WiFi Network Sharing
Encode WiFi credentials (SSID, password, encryption type) to allow guests to connect to your network by scanning a code.
Two-Factor Authentication Setup
Generate TOTP provisioning QR codes for authenticator apps like Google Authenticator and Authy using the otpauth:// URI scheme.
Pro Tips
Use the lowest error correction level (L = 7%) for digital displays and the highest (H = 30%) for printed materials that may get damaged.
Maintain adequate quiet zone (white border) around the QR code — at least 4 modules wide for reliable scanning.
Test your QR codes with multiple scanner apps and devices before deploying to production.
For URLs, use a URL shortener to reduce data density and create smaller, more easily scannable QR codes.
All QR code generation is performed entirely in your browser. The data you encode is never transmitted to any external server, ensuring privacy for sensitive content like WiFi passwords and contact information.
