Rfid Based Door Access Control

Authorised people are provided with unique tags using which they can access that area.

Rfid based door access control.

Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects. In this post you are going to learn about how to build an rfid based access control system using arduino. The project arduino and rfid based door access system is basically an access control system and can be placed where authorize entry is compulsion like office school etc. Using this system authorization of personnel is carried out with an rfid card and only those with access can enter a secured area.

A rfid based door lock or access control system is based on some simple concepts. In this post you are going to learn about how to build an rfid based access control system using arduino. Rfid based technology is widely used in today s market and you ve probably at least heard of it before this article. We store a set of rfid card data in our system say 3 or 10 rfid card data.

A team of five young engineers stuck in alathur during the lockdown has developed an access control system based on radio frequency identification rfid for mosques to manage the covid 19. The security of any organisation is a priority for the authorities. This rfid based security system is based on micro controller at89c52 and comprises a rfid module a lcd module for displaying the status and a relay for opening the door. 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.
