Rfid Based Door Access Control

In this post you are going to learn about how to build an rfid based access control system using arduino.

Rfid based door access control. 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. A radio receiver and transmitter. The security of any organisation is a priority for the authorities. Access control panel hardware is needed to open the lock or door which is only done when the proper access is granted to each authorized cardholder.

An rfid tag consists of a tiny radio transponder. Authorised people are provided with unique tags using which they can access that area. The security concern is for the. 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.

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. Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects. A rfid based door lock or access control system is based on some simple concepts. Using this system authorization of personnel is carried out with an rfid card and only those with access can enter a secured area.

One of its renowned applications is a smart door lock system to protect the valuables and secrets behind the. When triggered by an electromagnetic interrogation pulse from a nearby rfid reader device the tag transmits digital data usually an identifying inventory number back to the reader.

Fig 1 shows a user trying to open the door by placing an rfid tag near the rfid reader.

In the previous post you learned about rfid and keypad based door lock and alert system using arduino in which user had to scan the right tag and enter the right password to open the door lock and the system also sends us the confirmation message. 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. In this post you are going to learn about how to build an rfid based access control system using arduino. Rfid security access control system using 8051 microcontroller is an rfid technology based security system.
