Wi-Fi QR code for guests
Let visitors join the network by pointing a camera at a card. No spelling the password aloud, no typing on small screens, and nothing uploaded anywhere.
What should the QR code contain?
Private by design. Everything is encoded in this browser tab. Nothing you enter is sent to LocateKit, and static codes carry no redirect and no expiry.
Stays in this tab
- The payload is encoded only by this browser.
- No tracking redirect is added to the code.
- PNG and SVG downloads unlock after a decode check.
- Static codes never expire on our side.
Wi-Fi network: Share a network name and password.
What the code holds
A Wi-Fi QR code is a short join record, not a secret handshake. It carries the network name, the security type, the password, and a flag for hidden networks. Phone cameras on current iOS and Android recognise the format and offer to join with one tap. No app and no internet connection is involved, because the whole record sits inside the symbol.
Four steps to a working card
- Enter the network name exactly. Copy the SSID character by character, including capitals, spaces, and punctuation. A near match does not connect.
- Pick the security type. WPA or WPA2 Personal covers almost every current home and office network. WEP is for old hardware only, and Open means no password.
- Type the password and set the hidden flag if needed. Without the flag, a phone looks for a broadcasting network with that name, finds nothing, and gives up.
- Download and test with a second phone. Take the SVG for anything printed. Scan it yourself before the card goes on the wall.
Put guests on the guest network
Print the guest password, keep the main one private. Most routers offer a separate guest network that isolates visitors from shared folders, printers, and cameras on your LAN. It also gives you a password you can rotate without re-pairing every device in the house.
- Print the guest code, keep the main one off the wall. The two networks have different passwords, and only one belongs in public.
- Rotate the guest password on a schedule. A cafe that changes it quarterly reprints one card. A cafe that never changes it has shared the password with everyone who ever sat down.
- Never post the card online. A photo of the code on social media is the password published. Any decoder reads it back out of the picture.
Print it so it actually scans
Keep the symbol at least 2 cm on each side for a table card, larger for distance reading. A rough rule for posters: the code should span about a tenth of the scanning distance, so a code read from 2 metres wants roughly 20 cm. Leave the quiet zone, the blank margin around the symbol, clear, keep dark modules on a light background, and avoid curved or glossy surfaces that throw glare into the camera.
Error correction helps against smudges and wear, but it never rescues a code printed too small or with a logo stamped across the middle. Read SVG or PNG, which to download before ordering a print run.
