WiFi Share — Share WiFi Over an NFC Tap with a QR Code

What does WiFi Share do? link

WiFi Share turns a tap into guest WiFi access. When someone taps a Kitetag at your café, hotel, or office, they see a branded screen with a QR code. They scan it (or download it and open it in their photo viewer) and the phone recognizes the network and offers to connect.

NFC alone cannot make a phone join a WiFi network — iOS ignores WiFi NDEF records and Android needs a companion app. A QR code in the standard WIFI: URI format is the only reliable cross-platform path, and WiFi Share generates it for you.

When should you use WiFi Share? link

• Cafés, restaurants, and bars — guest WiFi without a chalkboard password
• Hotels and short-term rentals — in-room tap card for the network
• Coworking and offices — visitor and meeting-room WiFi
• Events and pop-ups — temporary network access for attendees

How do you set up WiFi Share? link

WiFi Share is a step in the Interaction Builder, so you add it inside an interaction rather than as a standalone app.

1. Open the Interaction Builder and click Add Step.
2. Under Display Content, choose WiFi Share.
3. Configure the fields:
   • Network Name (SSID) — exactly as your router broadcasts it (case-sensitive).
   • Security — WPA/WPA2/WPA3, WEP, or None (open network).
   • Password — hidden behind a show/hide toggle so it is not exposed over your shoulder.
   • Hidden network — check this only if the SSID does not broadcast.
   • Venue / Brand Name (optional) — shown above the QR code so Tappers know whose WiFi it is.
   • Instructions — short guidance, e.g. “Download the QR code, open it in your photo viewer, and your phone will offer to connect.”
   • Download Button Text — the label on the button that saves the QR image.
4. Watch the iPhone preview update on the right.
5. Save or Publish the interaction and assign it to a Kitetag Group.

What the Tapper sees link

The tap screen shows your venue name, the QR code, your instruction text, and a download button. On iOS 11+ and Android 10+ the phone camera or photo viewer detects the embedded network and offers to join. After downloading, the Tapper can continue through any remaining steps in the interaction.
