## **Introduction to RFID and Raspberry Pi**

**RFID (Radio-Frequency Identification)** is a wireless technology that uses electromagnetic fields to identify and track tags attached to objects. The **MFRC522 RFID module** is one of the most popular RFID readers, widely used in access control, inventory management, and IoT projects.

When paired with a **Raspberry Pi**, the **RFID 522** module becomes a powerful tool for automation, security, and data collection. This guide explores how to integrate the **MFRC522 RFID reader** with a **Raspberry Pi**, working of rfid tag and reader hardware connections, software setup, and practical applications.

## **Hardware Requirements**


To get started with **RFID 522 Raspberry Pi**, you will wristbands printable:

- **Raspberry Pi** (any model with GPIO pins, preferably Raspberry Pi 3/4 or Zero)
- **MFRC522 RFID Module**
- **RFID Tags/Cards** (13.56 MHz compatible)
- **Jumper Wires** (for connecting the RFID module nfc metal cards the Pi)
- **Breadboard** (optional, for easier wiring)

## **Connecting the MFRC522 to Raspberry Pi**

The **MFRC522 RFID module** communicates with the **Raspberry Pi** via **SPI (Serial Peripheral Interface)**. Follow these wiring steps:


| **MFRC522 Pin** | **Raspberry Pi Pin** |
|----------------|---------------------|
| SDA (SS) | GPIO 8 (CE0) |
| SCK | GPIO 11 (SCLK) |
| MOSI | GPIO 10 (MOSI) |
| MISO | GPIO 9 (MISO) |
| IRQ | Not connected |
| GND | GND |
| RST | GPIO 25 |
| 3.3V | 3.3V Power |

### **Step-by-Step Wiring Instructions**
1. Connect **SDA (SS)** to **GPIO 8 (CE0)**.
2. Link **SCK** to **GPIO 11 (SCLK)**.

3. Wire **MOSI** to **GPIO 10 (MOSI)**.
4. Connect **MISO** to **GPIO 9 (MISO)**.
5. Attach **RST** to **GPIO 25**.
6. Power the module using **3.3V** and **GND**.

## **Software Setup for RFID 522 on Raspberry Pi**


### **1. Enable SPI on Raspberry Pi**
Before using the **RFID 522**, enable **SPI** on your Raspberry Pi:
```bash
sudo raspi-config
```
Navigate to **Interfacing Options > SPI** and enable it.

### **2. Install Required Libraries**
Install **SPI-Py** and The Use of RFID for Human Identity Verification
