Tap in at the gate.
Tap out on the way home.
We're building DuoApp NFC plates for your site entrances. Someone taps their phone on the plate to check in, and taps again to leave - no picking a project, and it works where GPS struggles. Every plate carries a QR code too, for phones without NFC. It isn't available yet: register your interest and we'll keep you posted.
Interested? Let us know.
NFC Site Check-In is still in development. Tell us a little about your sites and we'll be in touch when there's news - it also helps us decide what to build first.
- No commitment and nothing to pay
- We'll contact you when there's news - no dates promised until we're sure
- Your notes go straight to the team building it
Arrive. Tap. Work. Tap. Home.
Tap in, tap out
A phone on the DuoApp plate at the entrance checks someone in. Tap again to leave.
No choosing a project
Each plate belongs to one site, so DuoApp knows exactly where they are.
Works where GPS doesn't
Basements, steel frames and dense city sites. The tap proves they were at the gate.
Builds on what you have
Check-ins go into your existing Site Attendance: the map, the fire roll and the records.
A plate at the gate. A tap on the way in.
A plate at each entrance

Tap or scan

They appear on the attendance map and fire roll straight away.
What we're building.
- Tag
- NTAG 424 DNA secure NFC
- Security
- Every tap creates a unique signed code that DuoApp checks, so copied plates and replayed taps are refused
- Without NFC
- QR code on every plate
- Phones
- iPhone XS or later, and Android phones with NFC
- No signal
- Taps are stored on the phone and synced when there's signal
Still in development. Plate design and pricing are being finalised, and details on this page may change before launch.
