## **Introduction to RFID and NFC**

**RFID (Radio Frequency Identification)** and **NFC (Near Field Communication)** are two groundbreaking wireless technologies that have transformed industries ranging from retail and logistics to healthcare and security. Both technologies enable contactless data transmission, but they differ in range, functionality, and applications. This article explores the fundamentals, differences, and real-world applications of **RFID and NFC**.

## **Understanding RFID Technology**


### **What is RFID?**
**RFID** is a wireless technology that uses electromagnetic fields to automatically identify and track tags attached to objects. These tags contain electronically stored information that can be read from a distance without direct line-of-sight.

### **Components of RFID Systems**

1. **RFID Tags** – Small chips with antennas that store data.
2. **RFID Readers** – Devices that send and receive signals from tags.
3. **RFID Software** – Processes and manages collected data.

### **Types of RFID**
- **Passive RFID** – No internal power source; relies on reader signals.
- **Active RFID** – Battery-powered for longer read ranges.
- **Semi-Passive RFID** – Uses a battery for certain functions but relies on reader signals for communication.


### **Applications of RFID**
- **Supply Chain & Logistics** – Tracking inventory and shipments.
- **Retail** – Anti-theft systems and smart shelves.
- **Healthcare** – Patient tracking and medication management.

- **Access Control** – Secure entry systems.

## **Understanding NFC Technology**

### **What is NFC?**
**NFC** is a subset of RFID that operates at a shorter range (typically less than 4 inches). It enables two-way communication between devices, making it ideal for contactless payments, data sharing, and smart device interactions.

### **Key Features of NFC**
- **Short-Range Communication** – Ensures security in transactions.
- **Two-Way Data Transfer** – Devices can send and receive data.
- **Peer-to-Peer Mode** – Enables device pairing (e.g., Android The Use of RFID for Human Identity Verification
