<h2>Introduction to RFID Technology</h2>

RFID cards represent a significant advancement in the realm of identification and access control systems. These cards utilize Radio Frequency Identification (RFID) technology to enable seamless communication between the card and a reader without the need for physical contact. The core principle involves the use of electromagnetic fields to automatically identify and track tags attached to objects. In the case of RFID cards, a small microchip and an antenna are embedded within the card, allowing it to transmit data when brought near an RFID reader. This technology has found widespread applications across various industries, including security, transportation, payment systems, and inventory management. The versatility and efficiency of RFID cards have made them a preferred choice for organizations seeking to enhance operational workflows and improve security measures.



<h2>How RFID Cards Work</h2>
The functionality of RFID cards hinges on a simple yet sophisticated process. Each card contains a unique identifier stored on its microchip. When the card enters the electromagnetic field generated by an RFID reader, the antenna within the card captures the energy from the field, powering the microchip. Once activated, the chip transmits its stored data back to the reader via radio waves. This entire interaction occurs within milliseconds, enabling quick and efficient data exchange. There are two primary types of RFID cards: passive and active. Passive RFID cards do not have an internal power source and rely entirely on the reader's energy to function. In contrast, active RFID cards contain a battery, allowing them to broadcast signals over longer distances. The choice between passive and active RFID cards depends on the specific application requirements, such as range and durability.



<h3>Key Components of RFID Cards</h3>
Understanding the components of RFID cards is essential to grasp their functionality. The microchip, often referred to as the integrated circuit (IC), is the brain of the card, storing all necessary data, including unique identification numbers and sometimes additional information. The antenna, typically made of copper or aluminum, is crucial for receiving and transmitting signals. These components are encapsulated within a durable material, such as PVC or composite, to protect them from physical damage and environmental factors.
