What Is a WiFi QR Code?

A WiFi QR code is a QR code that encodes your WiFi network's credentials — the network name (SSID), password, and security type. When someone scans it with their phone camera, their device automatically connects to the network without any typing.

This is the standard way to share WiFi access in restaurants, hotels, Airbnbs, offices, conference rooms, and events.

How to Create a WiFi QR Code (Free, 3 Steps)

Step 1: Open TooStamply's QR Generator

Go to TooStamply's QR Code Generator — no signup, no download, opens instantly in your browser.

Step 2: Select WiFi Type and Enter Your Details

  • Network Name (SSID): The name of your WiFi network (exactly as it appears in the WiFi list — case sensitive)
  • Password: Your WiFi password
  • Security Type: WPA/WPA2 (most common), WEP (old routers), or None (open network)
  • Hidden Network: Toggle on if your network is set to not broadcast its SSID

Step 3: Customize and Download

Add your logo, change colors, pick a shape, add a frame — then download as PNG (up to 2048px) or SVG for print-ready quality.

WiFi QR Code Format (Technical)

WiFi QR codes use a standardized encoding format:

WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;
  • T: Security type (WPA, WEP, or empty for none)
  • S: SSID (network name)
  • P: Password
  • H: Hidden (true/false, optional)

TooStamply generates this encoding automatically — you just fill in the fields.

Where to Use WiFi QR Codes

Restaurants & Cafes

Print on table tent cards, menu backs, or wall signs. Guests connect themselves — no staff interruption needed. A laminated A5 table card is the most durable format.

Best practice: Create a separate guest network (most modern routers support this). Name it something like "CafeName-Guest" and use a simple memorable password for the QR code. Your main network stays private.

Hotels & Hospitality

Print on welcome cards, key envelopes, or room info sheets. Guests connect on arrival without hunting for a password card or calling the front desk.

Airbnb & Short-Term Rentals

Print on a welcome frame near the door or on the fridge. Guests appreciate the instant connection. Update the QR code if you change your password (free to regenerate anytime).

Offices & Coworking Spaces

Display in reception, meeting rooms, and phone booths. Different QR codes for different networks (employee vs. guest vs. conference room). Print as A4 desk cards or A3 wall posters.

Events & Conferences

Print on registration badges, stage backdrops, or event programs. A 400x400px QR code on a badge is readable from arm's length.

Retail & Boutiques

Display at point of sale or fitting rooms. Customers who connect to your WiFi are more likely to share your products to social media while in-store.

Security Considerations

Use a Guest Network for Public QR Codes

Most modern routers (ASUS, TP-Link, Netgear, Eero, etc.) support a separate guest network that is isolated from your main network. Create a guest network specifically for QR code sharing:

  1. Log into your router admin panel (usually 192.168.1.1)
  2. Find "Guest Network" or "Guest WiFi" settings
  3. Create a separate SSID with its own password
  4. Enable client isolation (prevents guest devices from seeing each other)
  5. Generate the QR code for the guest network only

This way, if someone extracts the password from your QR code, they only have access to the guest network — not your main network or connected devices.

Who Can Read the QR Code?

The password is encoded in the QR code image. Anyone with a QR code reader app can read the raw data. For a public location, assume the password is public knowledge — design your network security accordingly.

Change Your Password Without Reprinting?

If you regenerate the QR code after a password change, you'll need to reprint physical displays. This is why keeping a simple, memorable guest password makes sense — you change it rarely (if ever) because the guest network is already isolated.

Scanning WiFi QR Codes — Device Guide

iPhone (iOS 11+)

  1. Open the Camera app
  2. Point at the QR code
  3. Tap the "Join Network" notification at the top of the screen
  4. Done — connected automatically

Alternatively: Settings → WiFi → tap the QR code icon next to "Other..."

Android (Android 10+)

  1. Open the Camera app
  2. Point at the QR code
  3. Tap the notification to connect
  4. Done

On Android 9 and earlier, use Google Lens or a QR scanner app.

Samsung Galaxy

Settings → Connections → WiFi → tap the QR code icon → scan

Windows (Windows 10/11)

Windows does not natively scan QR codes for WiFi connection. Users need a QR reader app, or can enter the credentials manually.

macOS

macOS does not natively scan WiFi QR codes. iPhone/iPad hotspot to macOS is a workaround, or use a QR reader app.

Download Format

  • PNG at 2048px — for most print sizes up to A4
  • SVG — for large format printing (A3, banners, signs) — scales infinitely

Design Tips

  • Add your business logo to reinforce branding
  • Include a "Scan for WiFi" call to action text above or below the code
  • Use high contrast — dark QR on light background scans most reliably
  • Laminate if displaying in high-moisture areas (kitchens, bathrooms, outdoor spaces)

WiFi QR Code vs. NFC Tag

For most businesses, WiFi QR codes win on cost and visual flexibility. NFC tags are useful in upscale settings where physical aesthetic matters and budget allows.

Frequently Asked Questions

How do I create a WiFi QR code?

Go to TooStamply's QR Code Generator, select the WiFi type, enter your network name (SSID), password, and security type (WPA/WPA2, WEP, or none). Click generate and download as PNG or SVG. Guests scan it and connect automatically — no typing.

Is it safe to share a WiFi QR code?

It depends on context. A WiFi QR code encodes your password — anyone who scans it (or copies the image and reads the encoded data) gets your password. For guest/public networks this is fine. For your main network, consider creating a separate guest network for the QR code. Never post a WiFi QR code that contains your main router password publicly.

Can Android phones scan WiFi QR codes?

Yes. Android 10 and later scan WiFi QR codes natively through the camera app. On Android 9 and earlier, a third-party QR scanner app is needed. Google Lens also reads WiFi QR codes on all Android versions.

Can iPhones scan WiFi QR codes?

Yes. iOS 11 and later (iPhone 5s and newer) scan WiFi QR codes natively through the built-in Camera app. Point the camera at the QR code and tap the notification that appears to connect automatically.

What WiFi security type should I choose for my QR code?

Choose WPA/WPA2 for most modern routers — it's the most common and most secure. Choose WEP only for very old routers (it's less secure). Choose "None" only for open networks with no password. When in doubt, check your router settings — most modern routers use WPA2.

Can I print a WiFi QR code for my business?

Yes — and this is one of the most valuable uses. Print your WiFi QR code on table cards, wall signs, receipts, or menu backs. Guests scan to connect without you needing to verbally give out the password. TooStamply generates high-resolution PNG (up to 2048px) and SVG for crisp printing at any size.
