Frequently Asked Questions
What is the benefit of Level H (30%) error correction?
Level H allows up to 30% of the QR code surface to be obscured, scratched, or covered by a logo while remaining 100% scannable.
Do these QR codes ever expire?
No! These are static QR codes that encode your data directly into the matrix pattern. They work forever without subscriptions or third-party redirect servers.

You can generate QR codes for URLs, plain text, Wi-Fi credentials (WPA/WPA2/WEP), and vCard digital contact cards, with adjustable Reed-Solomon error correction levels (L, M, Q, H) allowing up to 30% data recovery if damaged.
