WiFi QR Code for Cafes: Share Your Password Instantly

Your barista should not have to spell out the WiFi password 30 times before lunch. Make a QR code. Customers scan and connect instantly.

Quick Steps

No account. No watermark. Free forever.

Place	Size	Why It Works
Table tent cards	4 to 5 cm	Right where guests sit down and pull out their phone
Counter / register	6 to 8 cm	Customers connect while waiting for their order
Printed menus	3 cm+	Every guest handles the menu. Natural placement.
Entrance / front door	10 cm+	Regulars scan and connect before they even sit down
Receipts	2.5 cm+	Dine-in guests get the code right after ordering

Size rule: QR code width should be roughly 1/10th of the expected scanning distance. Bigger is always better for scannability.

Works on all phones. iPhone (iOS 11+) and Android (10+) scan QR codes with the built-in camera. No app needed.
Wrong security type? This is the most common mistake. Check your router. Most use WPA2. If you select the wrong one, the code will not connect.
Password changed? You need a new QR code. Use a guest network with a password you rarely change, and laminated sign holders so swapping is easy.
Hidden network? Android handles hidden SSIDs fine. Older iPhones may not. Consider a visible guest network instead.
Can guests see my password? It is encoded in the QR code data, but phones do not display it during connection. For security, use a separate guest network.
Brand it. Change the QR code colors to match your cafe. Dark brown on cream looks great. Just keep high contrast. Light on light will not scan.
