What is RFID in Raspberry Pi?

RC522 RFID modules are a simple add-on you can connect to a Raspberry Pi to read MIFARE tags and cards. This is potentially a great feature to include in a security system or any application where you need to identify an object or person without them pressing buttons, operating switches or other sensors.

How do I connect RFID-RC522 to ESP32?

Introduction to RFID-RC522 Module

  1. GND pin: connect this pin to GND (0V)
  2. VCC pin: connect this pin to VCC (3.3)
  3. RST pin: is a pin for reset and power-down.
  4. IRQ pin: is an interrupt pin that can alert the ESP32 when RFID tag comes into its detection range.
  5. MISO/SCL/TX pin: works as:

What is RC522 RC?

The RC522 is a 13.56MHz RFID module that is based on the MFRC522 controller from NXP semiconductors. The module can supports I2C, SPI and UART and normally is shipped with a RFID card and key fob. It is commonly used in attendance systems and other person/object identification applications.

Can ESP32 read RFID?

Introduction: ESP32 With RFID: Access Control This is possible through radio frequency identification or RFID from the English Radio Frequency Identification. Our goal, therefore, is to create a program in which we can either read an RFID card (or tag) or write the data to it.
