High Contrast: Use dark foreground on light background for optimal readability

Error Correction: Use higher levels (25-30%) for outdoor use or when damage is likely

Test Before Printing: Always verify QR codes work on different devices and apps

URL Shortening: Use short URLs to create simpler QR codes with better scanning reliability

Clear Instructions: Add "Scan with camera" text near QR codes for user guidance

Strategic Placement: Position at eye level and in well-lit areas for easy scanning

Format Choice: Use PNG for print materials and digital displays to maintain quality

Use high contrast colors, ensure minimum 2×2 cm size, test on multiple devices, and choose appropriate error correction levels for your use case.

Which error correction level should I choose?

Low (7%) for clean environments, Medium (15%) for general use, Quartile (25%) for outdoor applications, High (30%) for harsh conditions or when damage is likely.

For print: minimum 2cm x 2cm. For screens: at least 200x200 pixels. Larger codes scan more reliably. Choose size based on scanning distance and error correction level.

What's the difference between error correction levels?

Low (7% recovery), Medium (15%), Quartile (25%), High (30%). Higher levels create denser codes but survive more damage. Use Medium for most applications.

Can I customize QR code colors?

How much data can a QR code store?

Up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. Actual capacity depends on error correction level and character types used.

Do QR codes expire or become invalid?

QR codes themselves never expire. However, if they link to URLs or online content, that content may become unavailable over time. Static data (like text) remains permanent.
