ClasaMessenger

Stop calling roll. Start teaching.

Two ways to get attendance done in minutes, not periods: a one-tap digital register for teachers, or Clasa Cards that check in your whole school at the gate. Everything syncs to one live record.

Student tapping a Clasa card on a reader at the school entrance

At the gate

One tap. You’re marked present.

Students hold their Clasa Card to the reader on the way in. Their name appears on screen, and they’re recorded present in about a second. Nothing to learn, nothing to slow the line.

The 6-minute morning

Your entire school, checked in within 6 minutes.

Gates open. Students tap. Every class fills in live. By the time the last student walks in, attendance is already done—and not one minute of class time went to roll call.
