The 5-Minute WiFi Setup for Airbnb, Cafes and Coffee Shops
Your guests just dropped four bags in the hallway. The kid wants the iPad. The partner wants Google Maps. You read out a 22-character WPA2 password from a sticker behind the router, and someone gets it wrong twice. Welcome to hosting in 2026.
There is a much better way: a printed WiFi QR code your guests scan once and are connected. No typing, no typos, no shouting passwords across the room.
How a WiFi QR Code Actually Works
When a phone camera scans the QR code, your phone reads a string that looks like this:
That string contains four things: the network name (SSID), the security type (WPA/WEP/Open), the password, and whether it's a hidden network. The phone's OS recognizes the format and prompts the user to join — no app required.
This works natively on:
iPhone: iOS 11 and newer (released 2017+) — point the Camera app at the code, tap the banner that appears.
Android: most camera apps and Google Lens since Android 9 (2018+). Even older Androids work via a free QR scanner from the Play Store.
If your guests have phones from the last seven years, the QR code just works.
It's free, runs entirely in your browser, and never sends your password anywhere.
Step 2: Type your network name and password exactly
Case-sensitive. is not the same as . If you have a 2.4 GHz and a 5 GHz band with different names, generate one card for each — guests can pick whichever signal is stronger.
Try the tool mentioned above?
Open the related KuchhBhi tool and put the guide into practice.
WPA / WPA2 / WPA3: 99% of modern home and business routers. Pick WPA.
WEP: only for routers older than ~2015.
Open: no password (common for cafes that want zero friction).
Step 4: Hit Print
The tool generates a clean A5-sized card with the QR code, the network name printed below, and minimal branding. Print it on regular paper or sticker stock.
Step 5: Place the card where guests will look
Airbnb / vacation rental: inside the welcome book, on the fridge with a magnet, or framed on the entry table.
Cafe / restaurant: table tents on every two-top, or a single laminated card next to the till.
Coffee shop: counter sign at eye level — most customers will scan within 30 seconds of sitting down.
Hotel room: the night-stand or the inside of the room-service folder.
Where Hosts and Owners Get It Wrong
Putting the QR card next to the router. Guests need it the moment they walk in, not after they've already opened the closet. Place it where the bags drop, not where the router lives.
Forgetting to update the card after a password change. The QR encodes the password as it was at print time. If you rotate WiFi passwords (good practice for short-term rentals), regenerate and reprint at the same time.
Tiny QR codes on huge laminated signs. A QR code under ~3cm / 1.2 inches at the printed size is unreliable from a phone held at table distance. Bigger is better; 5cm / 2 inches is the sweet spot for table tents.
Not testing it once. Before the first guest arrives, scan your own QR card with both an iPhone and an Android. If your phone says "Join Network: …" — it works. If it says "open a website" — you generated a URL QR by mistake.
Security Questions Hosts Always Ask
Is it safe to print my password on a wall?
Yes — but with one caveat. The QR encodes your current password. If a guest takes a photo of the card, they have your password forever. For short-term rentals, the standard fix is a separate guest network with its own password, or rotating the password between stays. Most modern routers support a guest SSID in 30 seconds via the admin panel.
Can someone scan my card from outside?
Only if they have line-of-sight to your card and a camera that can read it from that distance. A QR card stuck on the fridge is far more secure than a password written on a sticker behind the router that anyone can photograph.
Does the QR generator send my password anywhere?
A reputable one shouldn't. Our WiFi QR Generator builds the QR code entirely in your browser using JavaScript — your SSID and password never leave your device. There's no upload, no analytics on the credentials, no account.
Frequently Asked Questions
Does it work for hidden (non-broadcast) networks?
Yes — there's a "Hidden network" toggle. Tick it if your router doesn't broadcast the SSID. The phone will still find and join the network.
Can I use one QR code for both 2.4 GHz and 5 GHz bands?
Only if both bands share the same SSID. If they have different names (common — HomeWiFi vs HomeWiFi_5G), print two cards.
What if a guest's phone is too old?
iOS before 11 (pre-2017) and Android phones from before 2018 may need a free QR scanner app. In practice, this is now a 1% case. Print the network name and password as a fallback at the bottom of the card just in case.
How many cards should I print for a cafe?
One per table at minimum, plus one large laminated version near the till. Smaller cards under glass at each table get scanned faster than a single sign across the room.
