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
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
