This document describes an RFID-based attendance system. It includes a block diagram of the system which uses an RFID reader module connected to a PIC microcontroller and LCD display powered by a power supply. The system works by detecting an RFID card within 10cm, checking the card information against a database, and increasing the attendance count for that student and storing it in the database if it matches. The system aims to automate attendance tracking in educational institutions for ease of use and data analysis.

4. Tags (or chips) consist of
two parts:
1) Antennae
2) Processor/ storage
Receives signal from reader
and gives a return signal with
ID number
Reader sends number to
database or server
This all is done using
WEIGAND protocol

7. ACTIVE:
Tag signal availability of 100ft.
HIGH signal strength
example : Railway cars on a track
PASSIVE:
Tag signal availability < 10 ft.
VERY LOW signal strength
( Widely used because very cheap to make)
TYPES

RFID card is detected by the reader module if it in the
range of 10 cm.
 After reading the card it checks the database.
 After checking database it decides that card is duplicate or
not.
 According to database it controller increases the count
for that specific lecture and store it in database

15.  This project is a full system for student monitoring in colleges, and high
education institutes.
 The device is supported with friendly using software for data analysis and
previewing .
 Lecturers need no more wasting time, and effort to have their Attendance
Register .
 Attendance Register now, easily uploaded to Database.
