The problem
Calling out names in a lecture hall costs several minutes per class, and produces attendance sheets that administration then has to re-enter by hand.
The solution
AppelNFC replaces the roll call with a card tap. Student cards already carry an NFC chip: the teacher holds the card near the phone and attendance is recorded instantly.
- NFC attendance — reads the student card chip, no manual entry.
- Automatic records — attendance goes straight to the database, removing re-entry and transcription errors.
- Real-time tracking — the teacher watches the roll fill up during the session.
- Export to administration — generates and sends the attendance report at the end of class.
- Group management — add or remove students, adjust schedules.
Implementation
A second-year engineering project, built in Kotlin with Android Studio. Badge reading
relies on Android’s NfcAdapter API, and attendance records are stored in a Firebase
database, which avoids hosting a dedicated backend for a project of this size.
