Frequently Asked Questions
Do these QR codes expire?
No. The QR code encodes your data directly, so it works forever and does not depend on any server or subscription. (This differs from 'dynamic' QR services that redirect through their own domain.)
What can a QR code contain?
Commonly a URL, but also plain text, contact details (vCard), Wi-Fi credentials, phone numbers, or email addresses. Most phone cameras scan them automatically.
Is there a limit on how much data a QR code can hold?
Technically a QR code can hold up to ~4,000 characters, but the more data it stores the denser and harder to scan it becomes. Short URLs scan most reliably.
