Frequently Asked Questions
Do these QR codes ever expire?
No. These are direct static QR codes where the target URL or text is mathematically encoded into the pixel matrix. They remain permanently scannable.
Can I generate a Wi-Fi QR code for guests?
Yes! Select the Wi-Fi mode, enter your network name and password, and guests can scan the code with their smartphone camera to instantly connect without typing credentials.
What is Error Correction Level?
QR error correction allows codes to remain readable even if up to 30% of the symbol is obscured or damaged. Higher levels (Q and H) are ideal for printing or outdoor displays.
