RFID Based Attendance System using PIC Micro controller

Attendance needs to be taken at various places including colleges, school for students and in the industries for the login logout time of employees. The mostly attendance system is manual and it is taken on paper, it consumes lot of time and many traditional Attendance system uses attendance register to note down the attendance Also the administrative person needs to maintain the attendance papers,Problem with existing attendance system is that sometimes wrong attendance can be entered. Also in colleges one student can give proxy attendance of another student. Probability of this is very less but it does happen.

So here we introduce RFID Based Student Attendance System.in this every student have RFID card which will be used to swapping on RFID reader which is placed on entry door or gate of class or company.Attendance will be taken if the encoded taggedID scannedmatches the taggedID stored in the memory. Otherwise, an error message will be displayed on LCD .

Block diagram:-

In the system of RFID(radio frequency identification) Based Student Attendance System ability to uniquely identify and take attendance of the students, in this users having RFID cardwhich is an IC chip that has unique hexadecimal or electronic product code (EPC) contained in it and only need to place their RFID tag on the EM-18 RFID reader to take attendance, andRFID redder is interfacing with PIC16F877A and then microcontroller willcheck the RFID tag 12 digits number is match with number predefine in micron roller memory and then attendance data will display on computer. Hence, it isavery time efficientsystem.

Attendance will be taken if the RFID cardtagged IDis, matches the tagged ID which is predefine in memory. Otherwise, an error message will be displayed on LCD.Then buzzer is turned on to give warning.
