Software Attendance Management Solution in PHP

This paper focuses on designing an automated attendance and access control system using Radio Frequency Identification (RFID) technology. The current methods used by companies to track employee attendance are often inefficient and prone to errors. The proposed system aims to improve the process by automatically recording the working hours of employees using RFID tags in the form of ID cards. The RFID system consists of three components: an antenna, a transceiver, and transponders (tags). The antenna transmits a signal to activate the tag, which then transmits data back to the antenna. Unlike barcodes, RFID tags can be read from a distance and through various materials. The ID number on the RFID tag corresponds to the user’s information stored in a database. The work’s objective is to efficiently manage and analyze attendance data according to workplace regulations. The implementation includes designing the system using a PIC16F876A microcontroller, simulating the system with Proteus software, and analyzing the performance of the hardware and software components. The paper’s scope encompasses its applicability in both educational institutions and industries, ensuring effective modeling and evaluation of the RFID-based attendance system.
