Rfid based smart attendance system

  1. 1. RFID BASED SMART ATTENDANCE SYSTEM Presented by Md. Afser Uddin Roll: 106 Reg: 2119 In guidance with Engr. Sanwar Hossain Assistant professor Head of the department Dept. of EEE Faridpur Engineering College
  2. 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. 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. 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. 5. The process of attendance system can be done by placing the card near the RFID reader
  6. 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. 7. RFID Tag RFID reader Computer System SMS/EMAIL
  8. 8. Hardware Requirments  8051 series microcontroller  RFID Tags and RFID Reader  LCD  Resistor  Capacitor  Diodes  Transformer  Voltage Regulator  Switches
  9. 9. SOFTWARTE REQUIRMENTS Keil Compiler Embedded C or Assembly
  10. 10. CIRCUIT
  11. 11. SCHEMATIC DIAGRAM
  12. 12. 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
  13. 13. ADVANTAGES  Proxy attendance can be caught  Hardcopy of attendance sheet is reduced
  14. 14. THANK YOU ALL
