What Are QR Codes?

QR (Quick Response) codes are two-dimensional barcodes that can store various types of information and be quickly scanned by smartphones and QR code readers. They were invented in 1994 by Denso Wave, a Japanese company, and have since become ubiquitous in modern digital communication.

QR codes can store significantly more data than traditional barcodes and can be scanned from any angle, making them versatile tools for sharing information.

3. Email

Generate QR codes that automatically open email clients with pre-filled recipient, subject, and body. Great for contact forms or direct communication.

4. Phone Calls

Create QR codes that dial phone numbers when scanned. Useful for business cards or contact information.

Best Practices for QR Codes

1. Error Correction

When adding logos, use higher error correction levels (Q or H) to ensure the code remains scannable even with logo coverage.

2. Logo Guidelines

  • Use square logos with transparent backgrounds (PNG format)
  • Keep logos centered and appropriately sized (not too large)
  • Test scannability after adding logos
  • Ensure sufficient contrast between logo and QR code

3. Size Considerations

QR codes should be large enough to scan easily. Minimum recommended size is 2cm x 2cm (0.8" x 0.8") for printed materials. For digital use, ensure sufficient resolution.

4. Placement

Place QR codes in accessible locations with adequate white space around them. Avoid placing near edges or in areas that might be damaged.

5. Testing

Always test QR codes with multiple scanners and devices before finalizing. Different devices may interpret codes slightly differently.
