The document describes an RFID-based student attendance and parent alert system. The system uses RFID tags assigned to each student to automatically record attendance by reading the tags. It then sends SMS alerts to parents when students arrive at and leave school. The system aims to simplify attendance tracking and notify parents without requiring direct contact. It allows for automated, contactless attendance recording and real-time parental notification.

GSM Based Student Data Acquisition - Parent Alert
Systems
Introduction
Nowadays, due to the easy availability of almost all information on the
internet these days, students are less motivated to attend the lecture. This project is
to simplify attendance recordersystem by using Radio Frequency Identification
(RFID) technology. RFID based Parent SMS Alert and Attendance System is a
embedded based application that will be developed to overcome this problem.
With the RFID kit, the system will be developed by using Embedded technology
and database supportusing PC. The systems also have integrated with the RFID
Database Handling System for a fully functional system. The information from
RFID Database handling System will be used for attendance and for SMS Alert
also.
The RFID based Parent SMS Alert and Attendance System also interacts with
parents using SMS system. Therefore, the system functionality is not only records
the student attendance, but also sends alert SMS to their parents.

Choice of the Topic with Reasoning
Objective of Project
The objectives of this project are to simplify the attendance recorder system
and alert the parent by SMS system. The system is capable to display the student
attendance status. The system will provide SMS alerts to parents when the
respective student will enter or exit from school.
Scope of Project
This proposedsystem extract the useful information such as student entering
time and student ID card with a name from the RFID tag. Then using such
information the software system automatically updates the student’s attendance.
Secondly, the system sends alert SMS to respective student’s parent that the
student is entered in school.
Problem Statement
Nowadays, due to fast life style parents don’thave time to drop their
children at school, so mostly the small children also travel by bus or auto. As the
small children go by public transport, parent doesn’tknow whether child reaches at
schoolor not. To overcome suchproblem and to minimize parents’ tension, our
system will alert parent using SMS.
Taking attendance of a number of students manually is time consuming, so
we are going to generate automatic attendance system using RFID tags. Each
student will have a unique RFID tag; student will be identified using this tag.

RFID TAG:
The RF transceiver is the source of the RF energy used to activate and power
the passive RFID tags. The RF transceiver may be enclosed in the same cabinet as
the reader or it may be a separate piece of equipment. When provided as a separate
piece of equipment, the transceiver is commonly referred to as an RF module. The
RF transceiver controls and modulates the radio frequencies that the antenna
transmits and receives. The transceiver filters and amplifies the backscatter signal
from a passive RFID tag.
The Advantages of RFID Over Bar Coding
1. No "line of sight" requirements: Bar codereads can sometimes be limited or
problematic due to the need to have a direct "line of sight" between a
scanner and a bar code. RFID tags can be read through the materials without
line of sight.
2. More automated reading: RFID tags can be read automatically when a
tagged productcomes pastor near a reader, reducing the labor required to
scan a productand allowing more proactive, real-time tracking.
3. Improved read rates: RFID tags ultimately offer the promise of higher read
rates than bar codes, especially in high-speed operations such as carton
sortation.
4. Greater data capacity: RFID tags can be easily encoded with item details
such as id_no and name, class, etc.
