2. WHAT IS RFID?
RFID(Radio Frequency Identification) is one
type of electronic device includes small
antena and a chip
this device is used to transit information like
person, animals, books or any stuff between
reader and RFID tag using radio frequency

3. the operating frequency range of these device
mainly include low, mid and high ranges
low frequency range is 30kHz to 500kHz
Mid frequency range is 900kHz to 1500kHz
High Frequency range is 2.4MHz to 13MHz

4. WHY RFID?
We can use RFID technology to make a
database of every student entering into the
the classroom also calculate the time resides
in the class
In this proposed system every student is
allotted with an RFID tag

5. The process of attendance system can be
done by placing the card near the RFID
reader

6. HOW DOES IT WORK?
the reader coil generates an electromagnetic
field which couple into the coil on the RFID tag
The field generates a current in the transponder
which power it and also contain the transmitted
data

7. RFID Tag RFID reader
Computer
System
SMS/EMAIL

10. Hardware Requirments
 8051 series microcontroller
 RFID Tags and RFID Reader
 LCD
 Resistor
 Capacitor
 Diodes
 Transformer
 Voltage Regulator
 Switches

11. SOFTWARTE REQUIRMENTS
Keil Compiler
Embedded C or Assembly

12. CIRCUIT

13. SCHEMATIC DIAGRAM

14. HOW TO OPERATES
 After all connection switch on the circuit
 LCD displays “PLEASE SWIPE THE CARD”
 Place the RFID tag near the reader
 Reader Reads Data and Transmit to the controller
 Microcontroller compares the tag with the data
base
 If the tag is matched LCD displays
“AUTHENTICATED” and takes your attendance

15. ADVANTAGES
 Proxy attendance can be caught
 Hardcopy of attendance sheet is
reduced
