Complete Guide to QR Codes
What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that can store various types of data. Unlike traditional barcodes that hold data only horizontally, QR codes store information both horizontally and vertically, allowing them to hold significantly more data.
Key Features of QR Codes:
QR Code Types Explained
URL QR Codes
Direct users to websites, landing pages, or app download links. Most common type for marketing.
WiFi QR Codes
Allow guests to connect to your network by scanning - no password typing needed.
vCard QR Codes
Share contact information that can be saved directly to the scanner's phone.
Event QR Codes
Add calendar events directly to the user's calendar app.
Error Correction Levels
QR codes include redundant data that allows them to be read even when partially obscured. Higher error correction means more data redundancy but larger QR codes.
| Level | Recovery | Best For |
|---|---|---|
| L (Low) | ~7% | Clean environments, maximum data capacity |
| M (Medium) | ~15% | General purpose, balanced approach |
| Q (Quartile) | ~25% | Industrial use, outdoor placement |
| H (High) | ~30% | Adding logos, harsh environments |
Best Practices
Design Guidelines:
- • Maintain high contrast between foreground and background (dark on light works best)
- • Include a quiet zone (white space) around the QR code
- • Minimum recommended size is 2x2 cm (0.8x0.8 inches) for print
- • Test with multiple devices before mass printing
- • Use SVG format for print materials to ensure crisp edges at any size
Common Use Cases
- Marketing: Link to websites, promotions, or app downloads
- Business Cards: Share contact details instantly with vCard codes
- Restaurants: Digital menus, WiFi access for customers
- Events: Ticketing, check-ins, and schedule sharing
- Retail: Product information, reviews, and pricing
- Education: Link to resources, videos, or interactive content
Frequently Asked Questions
How much data can a QR code hold?
Up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. However, more data means a denser, harder-to-scan code.
Do QR codes expire?
Static QR codes (like those generated here) never expire. They contain the data directly. Dynamic QR codes (which redirect through a service) may expire based on the service terms.
Can I add a logo to my QR code?
Yes, but use high error correction (H level) to ensure the code remains scannable. The logo should cover no more than 30% of the QR code area.
