In this tutorial, we are going to learn how to use RFID/NFC with Arduino. The RFID/NFC system includes two components: reader and tag. There are two popular RFID/NFC readers: RC522 and PN532 RFID/NFC reader. This tutorial focuses on RC522 RFID/NFC reader. Building an RFID access control system with an RC522 RFID module and an I2C LCD display is a fantastic project for beginners in Arduino. Not only does it teach you about interfacing different modules, but it also provides a practical application that can be expanded and customized for various uses.
In this beginners guide, you will learn how to connect an RFID reader module to an Arduino Uno and read tag information from RFID cards and tags. We will go over the components needed, how to wire up the circuit, example Arduino code to interface with the reader, and testing procedures. The MFRC522 supports three different communication protocols: SPI with Speed up to 10Mbit/s. I2C interface with speed up to 400kBd in Fast mode and up to 3400kBd in High-Speed mode. RS232 Serial UART with speed up to 1228.8kBd. The RC522 module usually comes with an RFID card and a key fob.RC522 RFID Reader Module. RC522 is a Multi-communication RFID Module for Arduino and Microcontrollers. The RC522 is known as MFRC-522 due to its NFX semiconductor microcontroller. The module allows the developers to interface it with any other SPI, I2C, and UART based microcontrollers.
Using I2C to Communicate with RFID Reader. As mentioned above, it is possible to use I2C instead of SPI in communicating with the RC522 RFID reader module. To enable I2C, we must cut the connection of the trace on the board to pin 1 on the IC. This can be done by drilling a hole on a board as shown by user Renate-USB of the Arduino community.
In case it’s your first time using LCD i2c Screen here’s a tutorial: Arduino LCD I2C simple use and direct write from serial monitor. The RFID-RC522 will permit you to read RFID Tags, identify their IDs, you can use it in door lock projects, garages, safes..In this guide, we will learn how to Interface the RFID MFRC522 with ESP32 and how to read the RFID tags and display it on a serial window using ESP32 and Arduino IDE.

So, that’s all about how to use the PN532 NFC RFID module with the Arduino and how to use all the three interfaces or modes UART, I2C, and SPI. In my upcoming tutorial, I will use the same PN532 RFID module with the Nodemcu ESP8266 and Google Spreadsheet.
The Qwiic RFID ID-XXLA is an I2C solution that pairs with the ID-LA modules: ID-3LA, the ID-12LA, or the ID-20LA, and utilizes 125kHz RFID chips. Let's take a look at the hardware used for this tutorial.
