Frequently Asked Questions
Does a generated QR code expire?
No. This tool creates a static QR code that encodes exactly what you entered, so it never expires. That said, if the URL it points to stops working, the QR code obviously can't take you anywhere useful anymore.
How does a Wi-Fi QR code work?
It's encoded in a standard format (WIFI:S:SSID;T:encryption-type;P:password;;) that a phone camera recognizes automatically, bringing up the Wi-Fi connection screen when scanned.
