Why a WiFi QR code

Typing a 20-character WPA2 password into a phone is clumsy. A WiFi QR encodes the SSID, password, and encryption type into a single image. Scanning it with any modern phone (iOS 11+, Android 10+) prompts “Join network?” — one tap, connected. Perfect for coffee shops, Airbnbs, offices, home routers, and conference rooms.

The format

WiFi QR codes use a simple text encoding called the WiFi Network Configuration format:

WIFI:T:WPA;S:MyNetwork;P:supersecret;;

Where T: is the encryption type (WPA, WEP, or nopass), S: is the SSID, P: is the password, and the double semicolon terminates the block. Special characters (\, ;, ,, :, ") must be escaped with a backslash.

Step 1: Generate the QR

  1. Open the WiFi generator.
  2. Enter your SSID exactly as it appears (case-sensitive).
  3. Enter your password.
  4. Pick your encryption type — WPA/WPA2/WPA3 are all handled by the WPA option; WEP only if you have an old router; nopass for open networks.
  5. Optionally tick “hidden network” if your SSID doesn't broadcast.

Step 2: Style it

Abundera QR offers 40 templates. For a guest-facing card I recommend Pastel or Corporate — readable at arm's length, friendly at a glance. Add a logo (the built-in WiFi icon works), set error correction to H (allows damage and logo overlay), and download as PNG for screens or PDF for print.

Step 3: Use the Business Card Designer

Click “Design WiFi card” to wrap your QR in a printable 3.5 × 2 in card with the network name, password, and a friendly “Scan to join” label. Export at 600 DPI as PDF; send to any print shop or run through a home printer on business-card stock.

Security notes

A WiFi QR embeds your password in plaintext inside the image. Anyone who photographs the printed code can read it with any QR scanner. Don't post your primary WiFi QR in a public window — use a guest network instead and rotate its password periodically. For truly sensitive networks, use 802.1X with per-user credentials, not a shared PSK.

Privacy note

Abundera QR does all of this in your browser. Your WiFi password never leaves your device — we have no server to receive it. Read the full privacy policy.
