RFID Based Students Attendance and SMS Notification System

Abstract

Main objective of RFID based Attendance System project is to take the attendance of students or employees. Notification sends to parents or authority. To demolish the flaws associated with the manual attendance system. Radio-frequency identification (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. RFID chips contain a radio transmitter that emits a coded identification number when queried by a reader device. Some RFID tags can be read from several meters away and beyond the line of sight of the reader. The application of bulk reading enables an almost-parallel reading of tags. This small type is incorporated in consumer products, and even implanted in pets, for identification. in this project we use RFID-522 as rfid card reader, Sim-800L as sms notifier and Arduino Mega as the controller of the project.
