Rfid based door access control project.

The master tag will act as programmer and you can use it to add or remove other tags. Working of rfid based access control system using arduino on starting the project for the first time it will ask you to define a master tag and whichever tag you will scan will be your master tag. An rfid system consists of two main components a transponder or a tag which is located on the object that we want to be identified and a transceiver or a reader the rfid reader consist of a radio frequency module a control unit and an. Rfid based security access system is designed in this project.

This rfid based access control system is built around arduino uno board rfid reader module solenoid lock and a few other components. We store a set of rfid card data in our system say 3 or 10 rfid card data. Rfid offers an important platform for identification of objects data collection and management of goods. When the person with the wrong rfid card whose data is not loaded in our system swipes his rfid tag access will be denied.

As the system uses rfid technology based identification it can be used to access secured areas like research centres defence sites etc. When the person with the right rfid card compatible to data preloaded in our program system come and swipes his rfid tag access will be granted. The circuit basically consist of arduino uno central control unit rfid receiver module rfid tag solenoid lock and few other electronics components like resistor capacitors diodes transistors etc. Circuit description of arduino and rfid based door access system.

About this project in this tutorial you will learn what rfid is how it works and how to make an arduino based rfid door access control system with counter. Upon detecting a transponder the terminal captures a photo and transmits the data including the uid and photo to the server through tcp ip connection. The rfid module works as sensor. Rfid is a non contact automatic identification technology that uses radio signals to identify track sort and detect a variety of objects including people vehicles goods and assets without the need for direct contact or line of sight contact as found necessary in bar code technology.

The circuit diagram of arduino and rfid based door access system is shown in figure 1. You can watch the following project video. Working of rfid based access control system using arduino on starting the project for the first time it will ask you to define a master tag and whichever tag you will scan will be your master tag. A rfid based door lock or access control system is based on some simple concepts.
