3. OBJECTIVE
• Automatic attendance recording system that allows
student to simply fill their attendance just by swiping or
moving their ID card on RFID reader .
• To monitor entry and exit time.

4. INTRODUCTION
• In this project, we have designed RFID Based Attendance
System using Arduino. EM-18 RFID Reader is a very simple yet
effective module. It is an RFID module and is used for scanning
RFID cards.
• It’s a new technology and is expanding day by day. Nowadays it
is extensively used in offices where employees are issued an
RFID card and their attendance is marked when they touch
their card to the RFID reader.

5. REQUIREMENTS
▪ HARDWARE REQUIREMENTS :
1. ARDUINO UNO
2. RFID READER
3. RTC MODULE DS1307
4. 20*4 LCD DISPLY
5. LED & BUZZERS
▪ SOFTWARE REQUIREMENTS :
1. PROTEUS 8
2. ARDUINO IDE

6. 1. ARDUINO UNO
• Arduino Uno is an open source microcontroller which its board
based on micro chip AT mega 328p microcontroller and which
is developed by Arduino.
• This board is supplies sets of analog and digital input and
output which may meet to various shield and other circuits.
Radio Frequency Identification (RFID) is widely known as
wireless non-contact use of radio waves which helps transfer in
data.

7. 2. RTC MODULE( DS1307)
• The DS1307 is an RTC Real Time Clock IC developed by Maxim
Integrated. It is a low cost, extremely accurate RTC IC with communication
over I2C Interface. An interesting feature of DS1307 RTC IC is that it has
integrated crystal oscillator and temperature sensor and hence you don’t
have to connect an external crystal
•DS1307 IC as the main component, several manufacturers developed
DS1307 RTC Modules with all the necessary components. Almost all
the modules available today consists of an additional IC, 24C32N (or
something similar). This secondary IC is an EEPROM IC of 32Kb size.

8. 3. RFID READER
• EM-18 RFID reader is one of the commonly used RFID reader to read
125KHz tags.
• It features low cost, low power consumption, small form factor and easy
to use.
• The module radiates 125KHz through its coils and when a 125KHz
passive RFID tag is brought into this field it will get energized from this
field.
• RFID CARD/ TAG – DATA CARRYING

11. Working of RFID Based Attendance System using
Arduino
• In this project, we have designed an RFID based attendance system
using Arduino. First, we store a set of RFID card data in our system.
You can store any number of RFID data, but we have only stored 5
RFID tag numbers.
• When the person with the correct RFID card comes & swipes his
RFID card, his arrival time will be stored on the system using the
EEPROM command displaying a “welcome” message on LCD.
• When the same person swipes his RFID card for the second time,
the system will save it as his leaving time displaying “See You”. The
interval between first card swap and second card swap is the total
working hours that are stored as data.

12. • ADVANTAGES
1. LOW COST
2. EASY TO MINTORED
3. THIS SYSTEM CAN BE USE IN MANY FIELDS WHERE THE RECORD OF
ATTENDANCE ARE STRICTLY MONITORED.
