FAQs
What can I encode in a QR code?
QR codes can encode URLs (up to 2,000 characters), plain text, WiFi credentials (SSID + password), vCard contact information, email addresses, phone numbers, SMS messages, GPS coordinates, and app store links. Choose the appropriate type for automatic device action.
What size should my QR code be?
For print materials, minimum 2×2 cm (0.8×0.8 inches) at 300 DPI. Business cards: 2-3 cm. Posters: 5-10 cm. Billboards: 50+ cm. Digital displays: 300×300 pixels minimum. Rule of thumb: QR code size should be at least 10% of scan distance.
What is error correction?
Error correction allows QR codes to remain scannable even if partially damaged or obscured. L=7% recovery (smallest code), M=15% (recommended), Q=25% (logos/branding), H=30% recovery (maximum durability). Higher levels create larger, more complex codes.
Do QR codes expire?
Static QR codes (like these) never expire - the data is permanently encoded in the image. However, if a QR code links to a URL, that webpage could be removed. Dynamic QR codes (from paid services) can expire, be edited, or tracked.
Can I add a logo to my QR code?
Yes, you can overlay a logo in the center, but it reduces scannability. Use High (H) error correction to maintain scanning ability. Logo should cover maximum 20-30% of QR code center. Always test scanning after adding logos.
Why won't my QR code scan?
Common issues: too small (minimum 2×2 cm), poor contrast (needs black on white or vice versa), damaged/wrinkled, poor lighting, camera out of focus, incorrect error correction for damage level. Ensure adequate white "quiet zone" border around code.
