Description

This RFID modules base on MFRC522 IC and that can read and write Mifare’s tags. The microcontroller and card reader uses SPI for communication. The card reader and the tags communicate using a 13.56MHz electromagnetic field.

Feature:

This RFID modules base on MFRC522 IC and that can read and write Mifare’s tags.
The microcontroller and card reader uses SPI for communication.
The card reader and the tags communicate using a 13.56MHz electromagnetic field.
The RFID MFRC522  module supports MF1xxS20, MF1xxS70 and MF1xxS50 tags.
The RFID MFRC522 module supports contactless communication and uses MIFARE higher transfer speeds up to 848 kBd in both directions.
RFID MFRC522 have compact design and small size 36x36mm.
Power can supply 3.3V or 5V.
This easy for connection to board with 5V, not need power regulator for 3.3V.
The antenna is built into the board. And it has a good sensitivity to a height of 25mm

Getting started with the RFID Reader/Writer NFC module MFRC522 13.56MHz

in this Tutorials we are going to deal with RFID Reader/Writer NFC module  this is simple and easy to connect with arduino where going to read the the RFID card target ID and print them to the serial Monitor and you can do different things using this RFID card reader so let’s start

Step1: Hardware required

• Arduino UNO
• RFID Reader/Writer NFC module
• Jumper wires

Step2: Connecting the Hardware

RC522 module             Arduino Uno,Nano                Arduino Mega
SDA (SS)                                   10                                                 53
SCK                                            13                                                 52
MOSI                                         11                                                 51
MISO                                         12                                                 50
IRQ                                         Not connected                              Not connected
GND                                        GND                                               GND
RST                                             9                                                   9
3.3V                                            3.3V                                              3.3V

Step3: Setting up the library

so before readin the RFID card tag we must have the library, so you can download it here. install the library by extracting that zipped file in the library folder  as shown below

Step4: Upload the sample sketch

open the sample sketch that is located in file>examples>RFID>cardRead. and upload it. as shown below

Step5: Testing the circuit

open your serial monitor by clicking on the icon in the right top corner(like search icon) slash your card to the RFID reader you will receive the card ID. see the picture below something like that
