Stick a WiFi QR code on the fridge. Anyone who points their phone at it joins your network — no password typed, no guessing whether it's a 1 or an l. iOS and Android handle this natively since 2018.
A WiFi QR code holds your SSID (network name), password, encryption type (WPA, WEP, or none), and a hidden-network flag. The standard format is WIFI:T:WPA;S:MyNetwork;P:hunter2;; — phones translate that string into a one-tap join prompt.
Restaurants tape it inside the menu. Airbnb hosts laminate one on the kitchen counter. Co-working spaces hang it by the door. Offices print one per meeting room. Anywhere people would otherwise ask "what's the WiFi?" is a good spot.
A WiFi QR code embeds the password in plain text. Anyone who photographs the code can extract the password — so don't post it publicly online if your network handles sensitive devices. For home and small-business guest networks, the convenience usually outweighs the risk.
A WiFi QR doesn't authenticate the user — anyone holding the code can join. It doesn't rotate the password either, so when you change the WiFi password, you need to regenerate the QR and reprint it. Plan for that if you reprint signage often.
The exact name as it appears in the WiFi list on a phone. Case-sensitive — "MyCafe" and "mycafe" are different networks to a phone.
WPA/WPA2/WPA3 for almost all modern networks. WEP only for very old gear (and you should replace that gear). "None" for fully open networks.
Special characters and spaces work — the encoder handles them. The password is embedded in the QR's pattern; treat the printed code itself as semi-sensitive.
Toggle the "hidden network" flag if the SSID is not broadcast. Most home and small-business networks broadcast; only flip this if you specifically know yours doesn't.
On the fridge, behind the bar, at reception. Phones scan from ~10 cm at PNG size 3×3 cm; for tables across the room, go bigger.
Sticker at each table or on the wall — guests connect in one tap without asking staff.
Laminate next to the router or in the welcome binder. Cuts "what's the WiFi?" messages to zero.
Print one per room. New attendees don't lose the first ten minutes onboarding to the network.
Family, friends, contractors — they scan and connect without you having to spell out a passphrase you barely remember.
