Executive Summary
Generating QR codes requires choosing between permanent static configurations and trackable dynamic systems. This guide leads you through the design parameters, error correction levels, and scannability validations.
1. Choose Static vs Dynamic Mode
First, decide if you require tracking data or editing target URLs after print. If you do, choose a dynamic QR code. If the target URL is absolute (like a personal portfolio page or WiFi network key), choose a static QR code.
2. Input the Target Information
Paste your target link, text, vCard data, or WiFi SSID. Double check for copy-paste typos, particularly on static QR codes where destination errors cannot be repaired after printing.
3. Enforce WCAG AA Contrast Checks
When customizing colors, verify foreground modules are darker than the background. Maintain a contrast ratio of at least 4.5:1. Avoid light pastel module designs, which cause scan failures under poor ambient light.
