Frequently Asked Questions

Find answers to common questions about QR code generation, usage, security, and technical specifications.

Are the QR codes free and do they expire?

Yes, all QR codes are completely free for personal and commercial use with no expiration. The codes themselves never expire as they contain encoded data. However, if your QR code links to a URL, ensure that URL remains active.

What's the maximum data capacity?

QR codes can store up to 4,296 alphanumeric or 7,089 numeric characters. However, more data creates denser codes that are harder to scan. We recommend keeping URLs under 100 characters and using URL shorteners for longer links.

What size should I print QR codes?

Print QR codes at a minimum of 2x2cm (0.8x0.8 inches). For distance scanning, use the formula: QR size = scanning distance ÷ 10. Always test with multiple devices before mass printing.

Why isn't my QR code scanning?

Common issues include low contrast, small print size, damage, poor lighting, or low camera quality. Ensure high contrast colors, adequate size, and test across multiple devices. Increase the error correction level for better reliability.
