How to Create a WiFi QR Code for Your Cafe, Hotel, or Office

Typing a 20-character WiFi password at a hotel check-in or coffee shop is annoying. A WiFi QR code eliminates the friction: guests scan, and they are connected. No reading out passwords, no mistyped characters.

Here is how to create one in under two minutes.

How WiFi QR Codes Work

A WiFi QR code encodes your network credentials in a special format that smartphones recognize:

WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;

When scanned:

iPhone (iOS 11+): Prompts to join the network automatically
Android (Android 10+): Opens the WiFi connection dialog
Older devices: Shows the network name and password as text

The password is in the QR code itself, so anyone who scans it gains access. Only use this for your guest network, not your admin or POS network.

Step-by-Step: Create a WiFi QR Code

Open QRCrack's WiFi QR code generator
Enter your Network Name (SSID) exactly as it appears in WiFi settings
Enter your Password (case-sensitive)
Select your Security type: WPA/WPA2 (most common), WEP (older), or None (open network)
Check "Hidden network" only if your SSID is hidden
Customize the design if desired
Download as PNG or SVG
Print and display

That is it. The generator handles all the encoding automatically.

Display Options by Venue Type

Cafe / Coffee shop: Print a 4" × 4" card and laminate it for each table. Include your logo and text like "Free WiFi — scan to connect." Place it near the sugar and condiments where customers naturally look.

Hotel / B&B: Create a tent card for each room with the room-specific or property-wide WiFi. Include the network name and password in text as backup for older devices. Print the QR at 3" × 3" minimum.

Office / Co-working space: Mount a printed sign or use a countertop display near the entrance. Create separate QR codes for your guest network and a high-speed network for tenants.

Restaurant / Bar: Add to the menu, table tent, or place a sticker under the menu header. "Scan for WiFi" next to the QR code is all the instruction needed.

Retail store: Post at the checkout counter. Customers waiting in line will scan rather than ask.

Design Tips

Print size: Minimum 2" × 2". For wall-mounted signs, 4" × 4" or larger.

Add a label: Always add text above or below — "WiFi: Scan to Connect" — so people know what the QR code does before scanning.

Include text fallback: Print the network name and password in small text below the QR code. Some guests have older phones or prefer to type.

Match your brand: Use your accent color for the QR modules. A WiFi sign in your brand colors looks more polished than a generic printout.

Laminate it: Especially in cafes and restaurants where cards get wet or greasy.

Security Considerations

Use a separate guest network. Never share your main business network. Create a guest SSID in your router settings that is isolated from your internal network and POS systems.

Change passwords periodically. If you change your WiFi password, you will need to generate a new QR code and reprint signs. For simplicity, keep the guest password simple and memorable.

Do not display in your window. Visible from the street means anyone outside can scan and join. Post inside the venue only.

WPA2 minimum. If your router still uses WEP, upgrade. WEP is trivially crackable and offers no real security.

What About iOS and Android Compatibility?

iOS 11+ (iPhone 7 and newer) supports WiFi QR codes natively through the camera app. No app needed. When scanned, a banner appears asking to join the network.

Android support varies by manufacturer but is generally available from Android 10+. Google Lens also reads WiFi QR codes on older Android versions.

For maximum compatibility, always include the network name and password as text alongside the QR code.
