<h2>Introduction to NFC Technology</h2>

NFC, or Near Field Communication, is a short-range wireless communication technology that enables data exchange between devices when they are brought within close proximity, typically less than 4 centimeters. NFC tags are small, passive devices that store information and can be read by NFC-enabled smartphones, tablets, or other readers. These tags are embedded with microchips and antennas, allowing them to communicate with compatible devices without requiring an internal power source. The technology operates at 13.56 MHz and supports data transfer rates up to 424 kbit/s, making it ideal for quick, secure interactions. NFC is a subset of RFID (Radio-Frequency Identification) technology, specifically designed for peer-to-peer communication and simplified data sharing. As the Internet of Things (IoT) continues to expand, NFC tags are becoming increasingly integral to everyday applications, from marketing to access control.


<h2>How NFC Tags Work</h2>
NFC tags function based on electromagnetic induction. When an NFC-enabled device, such as a smartphone, is brought near an NFC tag, the device's reader emits a radio frequency field that powers the tag's microchip. This energy allows the tag to transmit stored data back to the reader. The communication is one-way for passive tags (the most common type), meaning they do not have their own power source and rely entirely on the reader for operation. Active NFC tags, which are less common, have their own power supply and can initiate communication. The data stored on NFC tags can include URLs, contact information, commands, or other small amounts of data, typically ranging from 96 bytes to 4 kilobytes depending on the tag type. The simplicity and efficiency of this process make NFC tags highly versatile for various use cases.

<h2>Types of NFC Tags</h2>

NFC tags are categorized into five main types based on their capabilities and compatibility, defined by the NFC Forum (a standards organization). Type 1 tags are based on ISO/IEC 14443A standards, offering read and write functiona The Use of RFID for Human Identity Verification
