RFID-Based System for School Children Transportation Safety Enhancement

Abstract

RFID, short for Radio Frequency Identification, is a member of the Automatic Identification and Data Capture (AIDC) technology family, offering a rapid and dependable means of identifying various physical objects. This system is particularly valuable for security purposes, enabling the distinction between authorized and unauthorized individuals. It finds applications in real-time systems, such as tracking attendance in companies and industries to verify authorized personnel. Additionally, RFID is increasingly integrated with biometric technologies for enhanced security. The core components of an RFID system are the Transponder (tags attached to objects) and the Interrogator (RFID reader), which communicate wirelessly without requiring a direct line of sight.
In this project, the RFID module reader typically comprises a module with a transmitter, receiver, a control unit, and a coupling element (antenna). This module interfaces with a microcontroller, and when an RFID card is brought near it, the data on the card is read and displayed on an LCD screen. If the data on the card matches the information stored in the program memory, an authorized message is displayed. If there is no match, an unauthorized message is shown. Upon receiving an authorized message, the bus door automatically opens and closes after a brief delay. In the case of an unauthorized person, a buzzer is activated to alert individuals. The RFID module triggers the buzzer each time it reads data from the RFID card.
