How do you make an attendance system with RFID?

How to Operate RFID Based Attendance System Circuit?

  1. After making all the above connections, Switch on the circuit.
  2. On LCD it is displayed “PLEASE SWIPE THE CARD”.
  3. Place the RFID tag near the reader.
  4. Reader then reads the data in the tag and transmits to the controller.

How does RFID based attendance system work?

RFID attendance system provides wireless identification of stakeholders when they fall in the radiofrequency range of the RFID attendance reader. To mark the attendance automatically, the students or staff need to carry the RFID tag that contains unique information about them such as name/ID number/class/section.

What microcontroller is used in RFID?

This wireless RF Identification is used in many systems like RFID Based Attendance System, security systems, voting machines etc….8051 Microcontroller:

Feature 8051 8052
Interrupt sources 6 8

What is RFID in embedded system?

The Radio Frequency Identification (RFID) is an electronic device which includes a small antenna and a chip. This device is used for transmitting information between reader and RFID tag using radio frequency electromagnetic fields.

How do attendance cards work?

Attendance monitoring is very simple. This System assigns a unique card number for each employee. An employee places the RFID card within 10 cm distance from the RFID Reader. The RFID Reader writes down the time, date and type of departure / arrival.

What is a RFID module?

RFID or Radio Frequency Identification system consists of two main components, a transponder/tag attached to an object to be identified, and a Transceiver also known as interrogator/Reader. A Reader consists of a Radio Frequency module and an antenna which generates high frequency electromagnetic field.

What are the types of RFID?

Each RFID type can be either active (powered), passive (un-powered) or semi-passive (battery-assisted).

  • Low-frequency (LF) RFID tags: 30 KHz to 300 KHz.
  • High-frequency (HF) RFID tags: 3 to 30 MHz.
  • Ultra-high-frequency (UHF) RFID tags: 300 MHz to 3GHz.
  • Active, passive and semi-passive RFID tags.

Where is RFID used?

The most common RFID applications in hospitals are inventory tracking, control access, staff and patients tracking, tracking tools, tracking disposable consumables, tracking large/expensive equipment, laundry tracking, etc.

What is RFID based attendance system?

Main objective of RFID based Attendance System project is to take the attendance of students or employees. Microcontroller does the task of storing the attendance of the respective person in the Microcontroller memory.

How 8051 RFID works?

When a person put their RFID tag to RFID reader then RFID reads tag’s data and send it to 8051 microcontroller and then microcontroller compares this data with defined data or information.

How to program for RFID based access control system?

To program for RFID based attedance system, we first need to include header files and defines input and output pin and variables. After this we need to create a function for delay. Here we have some function that we have used in our program.

What is Radio Frequency Identification (RFID)?

The Radio Frequency Identification (RFID) is an electronic device which includes a small antenna and a chip. This device is used for transmitting information between reader and RFID tag using radio frequency electromagnetic fields. The operating frequency ranges of these devices include low, mid and high ranges.
