Types of QR Codes Explained
Definition: QR codes come in multiple types and models, each designed for different use cases, data capacities, and scanning environments.
The most important distinction is between static and dynamic QR codes. Static QR codes encode data directly — once created, the content cannot be changed. Dynamic QR codes use a redirect URL, allowing you to update the destination without reprinting. Beyond this, there are different QR code models (Model 1, Model 2, Micro QR) designed for different capacities and sizes.
Key points
- Static QR codes: permanent, no tracking, free forever
- Dynamic QR codes: editable destination, scan analytics
- Model 2 is the current standard (up to version 40)
- Micro QR codes are smaller for space-constrained uses
- Error correction levels: L (7%), M (15%), Q (25%), H (30%)
Frequently asked questions
What is the difference between static and dynamic QR codes?
Static QR codes encode the final URL directly and cannot be changed. Dynamic QR codes use a short redirect URL, so you can change the destination anytime without reprinting the code.
Which QR code type should I use?
Use static QR codes for permanent links (business cards, product packaging). Use dynamic QR codes when you need to update the destination or track scan analytics.
What are QR code error correction levels?
Error correction determines how much damage a QR code can sustain while remaining scannable. Level H (30%) is best for codes with logos, while Level L (7%) creates simpler, easier-to-scan codes.
