<h2>Introduction to RFID Technology in Key Fobs</h2>

RFID (Radio-Frequency Identification) technology has become a cornerstone in modern access control systems, particularly in the design and functionality of key fobs. These small, portable devices utilize RFID to enable seamless, contactless entry to buildings, vehicles, and restricted areas. The integration of RFID in key fobs offers a blend of convenience, security, and efficiency, making it a preferred choice for both residential and commercial applications. As wireless communication advances, the role of RFID in key fobs continues to expand, driving innovations in how we manage and secure our environments.


<h2>How RFID Key Fobs Work</h2>
<h3>Basic Operation Principles</h3>

An RFID key fob consists of a microchip and an antenna embedded within a compact housing. The microchip stores unique identification data, while the antenna facilitates communication with an RFID reader. When the key fob is brought within proximity of the reader (typically a few centimeters to several meters, depending on the frequency), the reader emits a radio frequency signal that powers the fob's chip via electromagnetic induction. The chip then transmits its stored data back to the reader, which verifies the information and grants or denies access accordingly. This entire process occurs in milliseconds, ensuring quick and efficient operation.

<h3>Types of RFID Used in Key Fobs</h3>
Key fobs primarily employ two types of RFID technology: low-frequency (LF) and high-frequency (HF). LF RFID, operating at 125 kHz, is commonly used for basic access control due to its reliability and resistance to interference from metals or liquids. HF RFID, typically at 13.56 MHz, offers enhanced security features and faster data transfer, making it suitable for more advanced applications like payment systems or multi-factor authentication. Some key fobs also incorporate NFC (Near Field Communication), a subset
