Automated Attendance System

AUTOMATED ATTENDANCE SYSTEM ’ is designed to collect and manage student’s attendance records from RFID devices installed in a class rooms. Based on the verification of student identification at the entrances system, the RFID tag can be embedded in the ID card of the individual. First to activate a new session(hour) the teacher swipes her RFID tag this marks a new attendance session during which the students can swipe once to increment their attendance. The RFID module operate in 125Khz range, when a tag passes through its vicinity, the module senses its presence and extracts its unique serial number and passes this code into microcontroller which matches the code to the correct person and increments the attendance of the particular person.

INTRODUCTION
The two major problems faced by organizations are time consuming manual attendance and wastage of electrical power. Our project is going to solve these problems by using RFID technology. The project is designed to store up to 50 card IDs but it is easily scalable up to 65000 card IDs but for that it requires external memory. Radio Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. So the RFID is a wireless identification.

Normally the RFID system comprises of two main parts: RFID Reader and RFID Tag. RFID Reader is an integrated or passive network which is used to interrogate information from RFID tag. The RFID Reader may consist of antenna, filters, modulator, demodulator, coupler and a micro processor.
