Frequently Asked Questions
Find answers to common questions about generating, customizing, and printing QR codes.
What is a QR code?
A QR code (Quick Response code) is a two-dimensional barcode that can be read by smartphones and QR code scanners. It stores information such as URLs, text, contact details, Wi-Fi credentials, and more. When scanned, the device reads the encoded data and takes the appropriate action.

Is my data safe and private?
Yes, 100%. Your QR codes are generated entirely in your browser using client-side JavaScript. No data is sent to any server or stored in a cloud database. Your privacy is completely protected.
How do I scan a QR code?
Most modern smartphones have built-in QR code scanners. Just open your camera app, point it at the QR code, and tap the notification that appears. On Android and iOS, you can also use dedicated QR code scanner apps.
What's the difference between error correction levels?
Error correction levels determine how much of the QR code can be damaged or covered while still being scannable. Low (7%), Medium (15%), Quartile (25%), and High (30%) allow increasingly damaged QR codes to be scanned.
Can I use these QR codes for business?
Absolutely! Our QR codes work perfectly for business use cases like marketing campaigns, product packaging, business cards, event tickets, menus, and more.
Do QR codes expire?
Static QR codes (like those for URLs, Wi-Fi, or contacts) don't expire. They will continue to work indefinitely as long as the destination data they point to remains valid.
