Tag-A-Log NFC Attendance
A offline mobile app that uses NFC tags to record attendance instantly, simplifying check‑ins for schools, events, and workplaces.
Tag‑A‑Log is a Flutter‑based mobile application that turns ordinary NFC tags into digital attendance tokens. Users simply tap their phone on a tag placed at the entry point, and the app records the timestamp, user ID, and location in real‑time. The backend, powered by Firebase Firestore and Cloud Functions, aggregates the data, provides analytics, and sends notifications to administrators.
Key features include offline‑first support (attendance data is cached locally and synced when connectivity returns), QR‑code fallback for devices without NFC, role‑based access control via Firebase Authentication, and a clean, responsive UI that works on both Android and iOS. The system is ideal for classrooms, conferences, or any scenario where quick, contactless check‑ins improve efficiency and accuracy.
By leveraging NFC technology, Tag‑A‑Log eliminates manual sign‑in sheets, reduces human error, and provides instant insights into attendance patterns. Its modular architecture also allows easy integration with existing HR or LMS platforms, making it a scalable solution for organizations of any size.
