The advantage of the rfid system is contact less and works without line of sight.
Rfid based door lock system ppt.
The rfid module works as sensor.
By using arduino it is easy to access and works very quickly while burning the code it is like plug and play device.
When we see sophisticated door management system s the price tag struck immediately along with the utility of course.
So we decided to test a simple and cheap prototype to see if such a robust system could be developed using the tool of our choice arduino uno.
After detecting and receiving rfid tag data through a serial interrupt routine microcontroller searches the nv ram for this number.
Generally traditional locks are heavy and that are not strong as they can damage simply by using some tools.
The basic necessity of security can be attained by designing various door locks such as mechanical locks or electrical locks.
A micro chip in a label used to transmit data when the label is exposed to radio wave.
Proposals from partner companies.
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.
Rfid based security and access control system is more secure and fast responded as compared to the other system like biometric.

Circuit description of arduino and rfid based door access system.
Rfid door lock with active tag.
The circuit diagram of arduino and rfid based door access system is shown in figure 1.
These kind of door locks are designed with one or more keys but for locking a large area various locks are needed.
Weimplemented a security system containing door locking systemusing passive type of rfid which can activate authenticate andvalidate the user and unlock the door in real time for secureaccess.

This rfid based access control system is built around arduino uno board rfid reader module solenoid lock and a few other components.
In countries like india such automatic systems are not cheap by any yardstick.
Rfid door lock with passive tag.
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.
3 1 basic explaination of rfid technology.
