Frequently Asked Questions
Do QRora QR codes expire?
No. All QR codes generated by QRora are static QR codes containing the raw encoded payload directly inside the matrix. They never depend on URL shorteners, redirect servers, or subscriptions, and will function forever.
How does the live roundtrip validation work?
When you customize colors, shapes, or logos, QRora rasterizes the canvas and runs the jsQR computer vision decoder against it. If contrast or logo obstruction causes the scanner to fail, a warning is immediately displayed.
Which format should I use: SVG or PNG?
Use SVG for printing, banners, business cards, and merchandise because vector graphics scale infinitely without pixelation. Use PNG for websites, social media, and digital documents.
