Attendance, without the friction

Take attendance in ten seconds, not ten minutes.

Présence runs a live check-in from a rotating QR code. Students scan, type their number, and they’re in — no app, no account, no passing a sheet around the room.

Students scan to check in

The roll-call tax

Every lecture starts with the same quiet theft of time.

Ten minutes, gone

A paper sheet circles a 200-seat hall and half the names are illegible by the time it returns.

Sign-ins for friends

One student signs in three absent mates. The sheet has no idea who actually sat there.

Spreadsheet archaeology

You transcribe scribbles into Excel on Sunday night, then hand-flag who’s slipping.

Tools that overreach

Most attendance apps harvest student emails, locations, and device fingerprints you never asked for.

How it works

Three steps. Zero setup for students.

01

Project the code

Open a session and put it on the lecture screen. A QR and a 6-character code appear — and rotate every few seconds.

02

Students check in

They scan or type the code at your URL, enter their student number, and confirm. No download, no login, no profile.

03

Watch it fill

Names stream in live as a count climbs on screen. Close the session and the matrix is already done.

What you get

An attendance system that respects everyone’s time — and data.

Live check-in

A rotating QR + code on the projector. Students are in within seconds of the slide going up.

Anti-proxy by design

The code changes every few seconds and one phone checks in one student. Screenshotting it to a friend doesn’t work.

Instant attendance matrix

Students × sessions, computed live. Change your policy and every percentage recomputes on the spot.

At-risk flagging

Présence surfaces students drifting below your threshold while there’s still time to reach out.

CSV & XLSX export

One click to the registrar’s format. Your corrections and excused absences travel with it.

Four languages

English, French, German, Italian — the check-in page meets students where they are.

Privacy is the product

We can’t leak what we never collect.

Présence was architected backwards from a privacy review. No student accounts, no analytics SDKs, nothing about a student that could follow them across courses.

  • Student roster number, per course
  • Raw check-in events you can audit
  • Your own teacher account
  • Student emails or names required
  • Location or device fingerprinting
  • Third-party analytics or trackers
  • Anything sold, ever
