Frequently asked questions
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that encodes text or URLs. Phones with a camera scan it and either display the text or open the link directly. They were invented in 1994 by Denso Wave for auto-parts tracking and became ubiquitous after iOS 11 added native scanning.
How do I scan it?
Most modern smartphones scan QR codes from the default camera app — point and tap the notification. No separate scanner app is needed on iPhones (iOS 11+) or recent Android devices.
What error correction level should I pick?
M (15%) is the standard default. Pick higher (Q or H) if the QR will be printed and might get scratched, partially obscured, or shrunk for a sticker. Higher error correction increases the density of the QR but lets it survive damage — useful for outdoor signs or product packaging.
