What Is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode invented by Denso Wave in 1994 that stores data in a grid of black and white squares. Unlike traditional barcodes that hold up to 20 characters, QR codes can encode up to 4,296 alphanumeric characters, making them capable of storing URLs, contact information, Wi-Fi credentials, and plain text. Smartphones scan QR codes using their built-in camera, which decodes the pattern and performs an action such as opening a website. According to Statista, global QR code interactions reached 26.95 million scans in 2025, driven by contactless payments, restaurant menus, and marketing campaigns. There are two main types: static QR codes that contain fixed data, and dynamic QR codes that redirect through a short URL, allowing the destination to be changed without reprinting. Dynamic QR codes also enable scan tracking with analytics on location, device, and time.
Static QR Codes
Traditional QR codes that contain fixed information. Once generated, the encoded data cannot be changed.
Dynamic QR Codes
Smart QR codes that redirect through a short URL. You can update the destination URL anytime without reprinting the QR code.
Trackable QR Codes
QR codes with built-in analytics that track every scan, providing insights on user behavior and engagement.
Why Track QR Code Scans?
Most free QR code generators create static codes with zero tracking capabilities. You print them, distribute them, and hope for the best with no data on what's working.
UseClick.io generates dynamic, trackable QR codes that give you complete visibility into:
- Total scans: See exactly how many times your QR code was scanned
- Scan locations: Know where your audience is with city-level precision
- Device types: Understand if users scan from iOS, Android, or other devices
- Scan times: Identify peak engagement hours and days
- Update destination: Change the URL anytime without reprinting the QR code

QR Code Best Practices
Follow these proven strategies to maximize your QR code scan rates and campaign success.
1. Optimize QR Code Size
The minimum recommended size for a QR code is 2 x 2 cm (0.8 x 0.8 inches). Larger codes are easier to scan from a distance.
2. Add a Clear Call-to-Action
Never assume people know what to do. Add text like "Scan for menu", "Scan to download", or "Scan for discount" near your QR code.
- "Scan to view our menu"
- "Scan for 20% off your first order"
- "Scan to watch the demo"
- "Scan to download the app"
3. Test Before Printing
Always test your QR code with multiple devices and scanning apps before mass printing. Check that it scans quickly and directs to the correct destination.
4. Ensure High Contrast
Use dark colors for the QR code on a light background. Avoid low-contrast combinations like light gray on white or dark blue on black.
5. Use Dynamic QR Codes for Marketing
Dynamic QR codes let you update the destination URL anytime without reprinting. This is crucial for campaigns, seasonal promotions, or fixing mistakes.
All UseClick.io QR codes are dynamic by default. Update your destination URL anytime, track scans in real-time, and get detailed analytics - all without reprinting.
