## Introduction

In the world of inventory management, asset tracking, and supply chain logistics, **RFID (Radio Frequency Identification)** and **barcode** technologies have been widely used for decades. While both serve similar purposes, they differ significantly in terms of functionality, efficiency, and application. This article explores the key differences between RFID and barcode systems, their advantages and disadvantages, and which technology may be best suited for specific use cases.

## What is RFID?

**RFID** is a wireless technology that uses electromagnetic does iphone have nfc to automatically identify and track tags attached to objects. An RFID system consists of three main components:

1. **RFID Tags** – Small electronic devices that store data and transmit it via radio waves.
2. **RFID Readers** – Devices that send and receive signals from RFID tags.
3. **RFID Software** – Processes the collected data for tracking and management.

RFID tags can be **passive (powered by rfid for library reader’s signal)** or **active (battery-powered)**. They offer **long-range scanning**, **durability**, and the ability to store more data than barcodes.

## What is a Barcode?

A **barcode** is a visual representation of data in the form of parallel lines (1D barcodes) or squares/dots (2D barcodes). Barcodes require a **direct line of sight** to be scanned using a laser or image-based scanner. They are widely used in retail, logistics, and healthcare due to their **low cost** and **simplicity**.

## Key Differences Between RFID and Barcode

### 1. **Scanning Method**
- **RFID**: Does not require line-of-sight scanning. Multiple tags can be read simultaneously.
- **Barcode**: Requires direct visibility and must be scanned one at a time.


### 2. **Data Storage**
- **RFID**: Can store **more data** (up to several kilobytes) and can be rewritten.
- **Barcode**: Limited data capacity (typically 10-20 characters) and cannot be modified once printed.

### 3. **Read Range**
- **RFID**: Can be read from **several meters away** (up to 100m for active RFID).
- **Barcode**: Must be scanned **within inches** of the scanner.

### 4. **Durability**
- **RFID**: Resistant to **du The Use of RFID for Human Identity Verification
