Static QR Code

A static QR code has data such as URLs or text directly encoded in its module pattern. Since it doesn't route through an external redirect server, there's no risk of links becoming invalid due to service termination or subscription expiry.

The drawback is that content cannot be changed once created. However, for fixed-content uses (company website URLs, Wi-Fi connection info, permanent contact details), static QR codes are more reliable and safe for long-term use.
