How to Make a Free WiFi QR Code for Your Business (30 Seconds)

A WiFi QR code is one of the simplest and most useful things any business can implement. Instead of printing your WiFi password on a card (which guests lose, staff have to find, and gets out of date when you change the password), a WiFi QR code lets guests connect with a single scan — no typing, no staff interaction, no friction.

This guide shows you how to create a free WiFi QR code in under 30 seconds.

What Is a WiFi QR Code?

A WiFi QR code encodes your network name (SSID), password, and security type into a scannable barcode. When a smartphone camera scans it, the phone automatically prompts the user to join your WiFi network. No app required — it works natively on all modern iPhones (iOS 11+) and Android devices (Android 10+).

Your WiFi password is encoded directly into the QR code image. At UnlimitedQRCodes.com, this encoding happens entirely in your browser — your password is never transmitted to any server.

Step-by-Step: Create Your Free WiFi QR Code

Step 1: Gather your WiFi details

You need three things:

• Network Name (SSID) — the name of your WiFi as it appears when searching for networks on a phone. Exact spelling and capitalisation matter.
• Password — your WiFi password. Case-sensitive.
• Security type — WPA/WPA2 for most modern routers (post-2004). WPA3 for newer routers. WEP for old routers. None for open networks.

Step 2: Click the WiFi tab

Visit UnlimitedQRCodes.com/wifi-qr-generator or click the WiFi tab on the homepage generator.

Step 3: Enter your network details

Fill in your network name, password, and security type. Your QR code generates instantly in the preview panel.

Step 4: Download and print

Download as SVG for professional framing and signage. Print at minimum 5cm × 5cm. Place in a branded frame near the router, on tables, or at reception.

Where to Place Your WiFi QR Code

Restaurants and Cafés

On tables alongside the food menu QR code. At the counter. On printed menus. The message "Scan to connect to free WiFi" removes all hesitation.

Hotels and Short-Stay

Framed in each room near the TV or desk. In the hotel lobby. In the restaurant and bar. For room-specific networks with unique passwords, use the bulk generator to create a different code per room.

Offices and Coworking Spaces

In reception and meeting rooms. On the guest network whiteboard (replaces the written-out password). At conference room desks for external visitors.

Healthcare Waiting Rooms

A contactless, hygienic way for patients to access waiting room WiFi without touching shared surfaces or asking staff.

Security Best Practices

• Use a dedicated guest network — most routers support a separate guest SSID that cannot access your main network devices
• Regenerate after changing your password — the QR code encodes your password at time of creation; update it whenever you change the password
• Treat the QR code like a printed password — it contains your WiFi credentials; don't display it in publicly accessible areas where you wouldn't display your password

Frequently Asked Questions

Is my WiFi password safe when creating a QR code?

Yes. UnlimitedQRCodes.com encodes your password entirely in your browser — it's stored in the QR code image itself and never transmitted to our servers. We have no record of your password.

Which phones support WiFi QR codes?

All modern smartphones: iPhones running iOS 11+ (iPhone 7 and newer) and Android phones running Android 10+. Both use the built-in camera app — no separate QR scanner app needed.

Can I create WiFi QR codes for multiple locations?

Yes. Use the bulk tab to upload a CSV with one row per network. Generate up to 30 WiFi QR codes at once — ideal for hotel groups, restaurant chains, and multi-floor offices.
