RFID technology is used for accessing data from a uniquely identify RFID card or tag by combining the radio frequency and microchip technologies i. With the help of RFID technology we can create smart systems that can be used personnel identification, product monitoring, individual or organisation security, transportation, maintenance of inventory and supply chain tracking.

The communication between the Reader and Card is using Radio Technology whereas the communication between RFID Reader and the host device like a microcontroller is through serial protocol. Active RFID Tags are battery powered and they have an electronically erasable and programmable memory. The coil acts as an antenna as well as the source of power through induction.

The microchip is a read only type memory and the user can only read the data that already stored by the manufacturer. For the microcontroller to function properly, we need to connect an Pin 31 of the microcontroller i. An LCD Display is used in this project to display the details of the card. The control pins are connected to P3. The next component we need to connect to the microcontroller is the RFID reader module.

Hence, we need to use the TX and RX pins for communication. Connect the RXD pin Pin 3. Similarly, connect the TXD pin P3. Connect the two input pins of the motor driver i. A motor is connected to output pins of the motor driver. The aim of this project is to design an RFID based security access control system using microcontroller, in which only authorised personnel are allowed access to a secure area.

The working of the project is explained here. With the help of suitable programming, we need to compare the received card no. If the received number is matched with the already stored number, then the microcontroller will display the name of the card holder on the LCD and activates the motor driver IC. As a result, the door is opened for a predefined duration after which the door is automatically closed. As the system uses RFID Technology based identification, it can be used to access secured areas like research centres, defence sites etc.

Limitations Even though RFID Technology is secure, the security can be increased by integrating other security measures like facial detection, finger print scanner etc.

As the card details are stored in the microcontroller, only a limited number of card details can be stored. Related Posts:.

Here, an AT89C52 Microcontroller is used and it is an 8-bit controller. In order to provide regulated 5V DC voltage to the controller we need to use power supply circuit. In other words to ensure the supply voltage does not falls below the threshold level of 1. To ensure smooth operation, we need to connect two ceramic capacitors in the range of 30pF to 40pF. This crystal oscillator is connected between pin 18 and 19 of the microcontroller.
