network protocols. By leveraging 5G and IoT-based sensors, real-time tracking will become
more efficient, reducing latency and enhancing data accuracy. Additionally, cloud storage
solutions can be further optimized to provide long-term historical data analysis for better
decision-making in student transportation safety.

Biometric authentication, such as fingerprint scanning or facial recognition, can also be


integrated into the RFID authentication system. This would eliminate the chances of students
using someone else’s RFID card and further ensure security in tracking. Furthermore, voice
recognition and speech-based alerts can be introduced for a more interactive and user-friendly
experience. The system could be modified to include audio alerts in case of emergencies,
allowing students to communicate directly with authorities in distress situations.
Lastly, incorporating blockchain technology into the system can enhance data security and
privacy. Blockchain can provide an immutable record of student attendance, vehicle location
logs, and emergency alerts, ensuring data integrity. This will prevent unauthorized access and
tampering with critical information. With continuous research and advancements in embedded
systems and IoT technology, this project has vast potential for widespread adoption in smart city
transportation, school buses, and corporate employee tracking systems.
