Interface RFID Reader Using Arduino
Hi Guys! In this project, we are going to find out about the RFID Reader (EM-18) and Arduino RFID Reader Interface. I will be interfacing the RFID Reader component with Arduino.
Introduction:
RFID or frequency Identification may be a means of communication over radiation. RFID Tags and RFID Cards are typically used for authentication and access management. You might have seen individuals swiping their identity cards at the doorway of their offices. The positive identification is in reality Associate in Nursing RFID Card that has the non-public data of the worker. The instant he/she swipes the cardboard, his sign up time are captured by a laptop. In this project, I’ll be victimization the favored EM-18 RFID Reader Module and a couple of RFID Cards. There’s another widespread RFID Reader referred to as RFID RC522. The major difference between EM-18 and RC522 RFID components are:
• EM-18 relies on a hundred twenty five kilocycle frequency Communication whereas the RC522 relies on 13.56 megacycle Frequency.
• Coming to the interface choices, EM-18 uses Serial Communication whereas RC522 uses SPI Communication. So, choice of the RFID Reader Module is incredibly necessary because it defines however you communicate with the module victimization Arduino.
Components Required:
- Arduino
- Virtual Terminal
- Compim Module
- RFID Cards
Circuit Design:
The Arduino pin 1 is attached with virtual terminal pin RXD. Pin 0 of Arduino is connected with compim module pin 2 and this pin 2 of compim module is also attached with virtual terminal received device. So this is the connection of this circuit.
Working:
The operating of the Arduino RFID Reader Module Interface is incredibly straightforward. When facultative the interface on the Arduino, we tend to should assign the remainder of the parameters related to UART Communication i.e. Baud Rate, Parity, Stop Bits and therefore the Size of the information.
After this, you may get a message as “Place the Card”. After you place your RFID Card on the RFID Reader, the RFID Reader Module it'll browse the info from the cardboard and sends the info to the Arduino over Serial Communication. This information is more analyzed by the Arduino and applicable messages are displayed within the screen.
Applications:
Interfacing RFID Reader with Arduino may be terribly helpful as you'll be able to implement a large vary of applications like:
• Access management
• Authentication
• E-Ticket
• E-Payment
• E-Toll
