<h2>Introduction to NFC and Bluetooth</h2>

<p>Near Field Communication (NFC) and Bluetooth are two prominent wireless technologies that have revolutionized how devices communicate over short distances. While both serve the purpose of enabling data exchange between electronic devices, they operate on fundamentally different principles, ranges, and use cases. NFC, a subset of RFID technology, functions at extremely close ranges—typically within 4 centimeters—using electromagnetic induction between antennas. It operates at 13.56 MHz and requires minimal power, often drawing energy from the initiating device. Bluetooth, on the other hand, is designed for longer-range communication, typically up to 10 meters (or more with advanced versions), using radio waves in the 2.4 GHz ISM band. It establishes personal area networks (PANs) and is widely used for continuous data streaming, such as audio transmission or file sharing. Understanding the distinctions between NFC and Bluetooth is crucial for developers, consumers, and industries leveraging these technologies for applications like mobile payments, IoT devices, and smart connectivity solutions.</p>



<h2>Technical Specifications and Operation</h2>
<h3>NFC Technology Overview</h3>
<p>NFC is based on RFID principles and enables two-way communication between devices when they are brought close together. It supports three modes: reader/writer, peer-to-peer, and card emulation. In reader/writer mode, an NFC device can read information from tags or cards, commonly used in access control or marketing. Peer-to-peer mode allows two NFC-enabled devices to exchange small amounts of data, such as contact details, while card emulation lets a device act like a smart card for payments. NFC operates at a data transfer rate of up to 424 kbps, which is sufficient for quick transactions but not for large files. Its key advantage is simplicity and security due to the short range, reducing the risk of unauthorized access. For instance, in mobile payments, NFC ensures that transactions only occur when the device is intentionally tapped against a terminal, enhancin The Use of RFID for Human Identity Verification
