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 exittime.

4. INTRODUCTION
•Inthis project,wehave designed RFID Based Attendance
System usingArduino.EM-18RFIDReaderisaverysimpleyet

6. 1. ARDUINO UNO
•Arduino Unoisanopensource microcontroller which itsboard
basedonmicro chipATmega328p microcontrollerandwhich
isdevelopedbyArduino.
•This boardissupplies setsofanalog and digital inputand
output which may meettovarious shield and other circuits.
Radio Frequency Identification (RFID)iswidely knownas
wirelessnon-contactuseofradiowaveswhichhelpstransferin
data.

7. 2. RTC MODULE( DS1307)
•TheDS1307isan RTC Real Time Clock ICdevelopedbyMaxim
Integrated.Itisa low cost, extremely accurate RTCICwith communication
over I2C Interface.Aninteresting featureofDS1307RTCICisthatithas
integrated crystal oscillatorandtemperature sensorandhence youdon’t
havetoconnectanexternalcrystal
•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 32Kbsize.

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 asdata.

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.
