<h2>Introduction to Wireless Identification and Communication</h2>


<p>In today's interconnected world, wireless technologies play a crucial role in various applications, from inventory management to access control systems. Among these technologies, <strong>RFID</strong> (Radio Frequency Identification) and <strong>BLE</strong> (Bluetooth Low Energy) stand out as prominent solutions for different use cases. While both enable wireless communication, they operate on fundamentally different principles and serve distinct purposes. This article provides an in-depth comparison between RFID and BLE technologies, examining their technical specifications, applications, advantages, and limitations to help you determine which solution best fits your specific needs.</p>

<h2>Understanding RFID Technology</h2>

<p><strong>RFID</strong> technology uses electromagnetic fields to automatically identify and track tags attached to objects. These tags contain electronically stored information that can be read from several meters away without requiring direct line-of-sight. The <strong>RFID</strong> system typically consists of three components: tags (which can be passive, active, or semi-passive), readers, and backend systems for data processing. Passive <strong>RFID</strong> tags draw power from the reader's electromagnetic field, making them cost-effective and maintenance-free but with limited range. Active tags have their own power source, enabling longer read ranges and additional capabilities. The technology operates across various frequency bands, including low frequency (LF), high frequency (HF), and ultra-high frequency (UHF), each offering different characteristics in terms of range, data transfer rate, and environmental penetration.</p>


<h2>Understanding BLE Technology</h2>



<p><strong>BLE</strong>, part of the Bluetooth 4.0 specification and later versions, is designed for short-range communication with significantly reduced power consumption compared to classic Bluetooth. This wireless personal area network technology operates in the 2.4 GHz ISM band and enables devices to communicate over distances typically ranging from a few centimeters to approxi The Use of RFID for Human Identity Verification
