5 min read · Updated June 2026
QR codes have gone from niche to universal — restaurant menus, business cards, payment systems, and marketing campaigns all rely on them. But not all QR codes are created equal. Understanding the types and best practices ensures your codes actually work.
Static vs Dynamic QR Codes
| Feature | Static | Dynamic |
|---|---|---|
| Content | Fixed at creation | Changeable after printing |
| Tracking | No analytics | Scan counts, location, device |
| Cost | Free | Usually paid service |

QR Code Content Types
- URL — most common; opens a website when scanned
- vCard — adds contact info directly to the phone
- WiFi — auto-connects to a network (SSID + password)
- Email — opens a pre-addressed email
- Phone — dials a phone number
- SMS — opens a pre-filled text message
- Plain text — displays any text content
Error Correction Levels
QR codes have built-in error correction that allows them to be read even when partially damaged or obscured:
| Level | Recovery | Use When |
|---|---|---|
| L (Low) | 7% | Maximum data, clean environment |
| M (Medium) | 15% | Standard use (default) |
| Q (Quartile) | 25% | Adding a logo in the center |
| H (High) | 30% | Harsh environments, heavy branding |
Higher error correction means the QR code can hold less data but is more resilient. Use level Q or H if you want to place a logo in the center.
Design Tips for Scannable QR Codes
- Always test before printing — scan with multiple devices and apps
- Maintain high contrast — dark on light works best; avoid low-contrast color combos
- Leave quiet zone — 4 modules of white space around the code
- Don't distort the code — keep it square, don't stretch or skew
- Size matters — minimum 2×2 cm for close-range scanning; larger for distance
- Shorten URLs first — shorter content = simpler code = easier to scan
Common Use Cases
Business Cards
A vCard QR code lets people save your contact info with one scan — no typing. Include name, phone, email, company, and website.
Restaurant Menus
QR codes replaced physical menus during COVID and stayed. Use dynamic codes so you can update the menu URL without reprinting.
Event Tickets
Unique QR codes per ticket enable fast check-in and prevent fraud. Each code contains a unique identifier verified at the door.
Product Packaging
Link to product details, reviews, warranty registration, or authenticity verification.
The Bottom Line
- Use static QR codes for permanent content; dynamic for campaigns that may change
- Choose error correction level based on your environment (Q or H for branding)
- Always test with real devices before printing
- Keep content short — shorter URLs make simpler, more scannable codes
- High contrast and a proper quiet zone are essential for reliability
