Cutting attendance roll-call from 12 minutes to 40 seconds

Roll-call is the most repeated task in a school day. A class of sixty takes ten to twelve minutes to mark by hand, twice a day, across every section — time that never reaches a lesson.

What changes with automated check-in

Aalo SchoolSuite supports three capture methods, and most campuses end up mixing them:

• QR cards — cheapest to issue and reprint, works with any Android handset.
• RFID tags — fastest at a gate, no line-of-sight needed.
• Face recognition — no card to forget, but needs decent lighting at the entry point.

Guardian alerts are the real win

The time saving is nice. The reason schools keep the system is the absence alert: when a student is not marked present by the cut-off, the guardian gets a push notification and an SMS fallback within the same minute.

Unexplained absences dropped by roughly a third in the first term at pilot campuses, mostly because parents found out at 8:15am rather than at 4pm.

A two-week rollout that works

1. Week one: issue cards to two year groups only, keep the paper register running in parallel.
2. Compare the two daily and fix the mismatches — they are nearly always duplicate profiles.
3. Week two: extend to the remaining year groups and retire the paper register.

Do not roll out to the whole school on day one. The parallel run is what surfaces bad data before it becomes a support ticket.
