Why QR codes "expire"
A QR code itself never expires — it is just a 2D barcode encoding a string. What expires is the destination URL if you use a redirect service that shuts down, pays-walls, or rate-limits after a trial period. To create a QR code that truly never expires:
- Use a static QR code (not a dynamic/redirect one).
- Encode a URL you control (your own domain or a stable permalink).
- Avoid URL shorteners with expiration policies.
