About — Free WiFi QR Code
A WiFi QR code is one of the most practical uses of the technology. Instead of spelling out your password letter by letter for every visitor, you create the QR code once and guests simply scan it to connect instantly. It has become standard in hotels, restaurants, cafés, coworking spaces and professional offices.
To create your WiFi QR code, enter text in the following format into the generator: WIFI:T:WPA;S:NetworkName;P:Password;; replacing NetworkName with your network’s SSID (exactly as it appears in the list of available networks) and Password with your WiFi key. For an open network with no password, use: WIFI:T:nopass;S:NetworkName;;
Once it’s generated, download your QR code as a PDF for perfect print quality. Laminate or frame it so it lasts. A well-placed WiFi QR code — at your entrance, on tables, at reception — cuts down on interruptions and improves your visitors’ experience.
The format supports WPA, WPA2 (the most common on modern routers), WEP (older routers) and open networks. The QR code is static: it doesn’t depend on any third-party server and will keep working forever, even if our site disappears. If you change your WiFi password, simply generate a new QR code.
Security tip: if your main network includes sensitive devices (servers, NAS drives, cameras), create a dedicated guest network on your router and share only that network through the QR code. You keep full control over your equipment while still offering internet access to visitors.
How do I format the text for a WPA2 WiFi QR code?
Use the format: WIFI:T:WPA;S:YourSSID;P:YourPassword;; — WPA also covers WPA2. Replace YourSSID with the exact name of your network (case-sensitive) and YourPassword with your WiFi key.
Does it work on iPhone and Android?
Yes. The built-in iPhone camera (iOS 11+) and almost all recent Android phones (Android 10+) recognise WiFi QR codes automatically and offer to connect with one tap, with no extra app.
Does a WiFi QR code reveal my password?
Technically, the password is encoded in the QR code and can be read by specialised apps. For public networks (cafés, hotels) that isn’t a problem. For business use, set up a separate guest network with its own password.
Where should I place a WiFi QR code in a restaurant or café?
The most effective spots are on tables (table stand or coaster), at the entrance, at the counter and on the menu. Print a high-quality PDF and laminate it so it survives spills. Make it at least 4 × 4 cm (about 1.5 inches) so it scans easily.
What if the WiFi QR code doesn’t work on some devices?
Check that the SSID and password don’t contain problematic special characters (quotes, backslashes). If they do, escape them with a backslash. Always test the QR code on several devices before printing in large numbers.
Step-by-step guide: create and roll out your WiFi QR code
1. Find your network details. Open your router’s WiFi settings (often printed on a label on the back of the device) and note the exact network name (SSID), including capital letters and special characters, as well as the security key.
2. Use the right security type. Most recent routers use WPA2 — write T:WPA in the text, which also covers WPA2/WPA3. If your network is open (no password), use T:nopass.
3. Generate and test before printing. Scan the QR code with at least two different phones (an iPhone and an Android) to check that the connection works automatically before printing in bulk.
4. Print and protect it. Download the QR code in high resolution (at least 300px for a table card, 800px for a poster), then laminate or frame it so it stands up to daily use.
5. Update it when needed. If you change your WiFi password, the old QR code will stop working: just generate a new one and replace the printed copies.
Use cases by industry
Hotels: a WiFi QR code in each room’s welcome booklet or at reception saves guests from asking for the password and reduces requests to staff, especially from international visitors unfamiliar with the local keyboard layout.
Restaurants and cafés: displayed on tables or at the counter, it encourages customers to stay longer, check out your social media or leave a review while they wait.
Coworking spaces and offices: a QR code in the meeting room or at reception lets visitors and external clients connect without calling the IT team every time.
Holiday rentals (Airbnb, cottages): included in the welcome book or displayed near the entrance, it saves guests time as soon as they arrive, especially for late check-ins with no contact with the host.
Trade shows and business events: a WiFi network dedicated to exhibitors or visitors, shared via a QR code on badges or signage, makes access simple for hundreds of attendees at once.
Best practices and mistakes to avoid
✅ Check capital letters and spaces. The SSID and password are case-sensitive — one missing capital letter prevents the connection even if the QR code looks fine.
✅ Prefer a guest network. For public use (shops, restaurants), create a WiFi network separate from your admin network to protect your internal equipment.
✅ Match the size to the scanning distance. A QR code on a table should be at least 3–4 cm wide; for a poster read from 1–2 metres away, allow at least 10 cm.
❌ Avoid unescaped special characters. Quotes, semicolons or backslashes in the SSID or password can break the WIFI: format and stop the code from being read.
❌ Don’t print at too low a resolution. A blurry or pixelated QR code (an enlarged screenshot) can become unreadable for phone cameras — always download the high-resolution file.
❌ Don’t reuse an old QR code after changing the password. The code becomes invalid and frustrates visitors; always generate a new one.
