Frequently asked questions
Do the QR codes expire?
No. Content is encoded directly in the pattern with no redirect service, so codes work permanently — but they also cannot be edited remotely.
Why can’t it read my image?
Make sure the image is sharp, the whole code is visible and there is no heavy distortion or glare. Cropping to the code can help.
Why won’t the camera start?
You need a device camera, an HTTPS page and permission granted in the browser.
Does it work on Android and iPhone?
Most recent phone cameras support Wi-Fi QR codes, but some devices or OS versions may not. Test with the phones your guests use.
What happens when someone scans it?
Most phones recognize a contact and offer to add it. Presentation varies slightly by device.
Will a logo stop the code scanning?
A logo forces level H error correction, which tolerates some coverage. Contrast, density and styling still matter, so test the exported image with real phones.
