<h2>Introduction to Mifare RFID</h2>


Mifare RFID represents one of the most widely adopted technologies in the realm of radio-frequency identification. Developed by NXP Semiconductors, the Mifare brand encompasses a family of integrated circuits (ICs) used in smart cards and tags for various applications. The term "Mifare" is derived from "MIkron FARE Collection System," highlighting its origins and purpose in efficient data management. As a high-frequency (HF) RFID system operating at 13.56 MHz, Mifare RFID enables secure, contactless communication between cards or tags and readers, making it indispensable in sectors like access control, public transportation, and payment systems. Its robustness, interoperability, and security features have cemented its position as a global standard, with billions of cards deployed worldwide.


<h2>How Mifare RFID Works</h2>
Mifare RFID systems function based on the principles of inductive coupling and electromagnetic fields. When a Mifare card or tag enters the proximity of a reader (typically within 10 cm), the reader's antenna generates a radio frequency field that powers the passive IC on the card through electromagnetic induction. This energy harvesting allows the card to transmit stored data back to the reader without an internal battery. The communication follows the ISO/IEC 14443 standard, ensuring compatibility across devices. Data is stored in memory sectors protected by cryptographic keys, such as those in Mifare Classic (using proprietary algorithms) or more secure versions like Mifare DESFire (employing AES encryption). This process facilitates quick, reliable transactions—often in less than 100 milliseconds—making it ideal for high-throughput environments like metro turnstiles or event ticketing.


<h2>Types of Mifare RFID Products</h2>
The Mifare RFID family includes several product lines tailored to different security and functionality needs. Mifare Classic, one of the earliest versions, is popular for basic applications like loyalty cards or low-security access systems but has known vulnerabilities. Mifare Plus offers enhanced security with AES encryption, serving as a upgrade path for Classic users. Mifare DESFire provides high security with m The Use of RFID for Human Identity Verification
