RFID keyfobs are small, portable devices that use Radio Frequency Identification (RFID) technology to provide secure access control and identification.They consist of a tiny chip and an antenna, which communicate with RFID readers using radio waves. When the keychain is placed near an RFID reader,it transmits its unique identification information, allowing access or triggering an action, like opening a door or unlocking a system.
RFID keychains are commonly used for contactless entry in offices, apartments, and secure buildings, as well as for public transportation or payment systems. They offer a convenient and secure alternative to traditional keys or cards, reducing the risk of theft or loss. The keychains are also durable, lightweight, and easy to carry, making them ideal for everyday use.
Overall, RFID keychains provide a simple yet effective solution for secure access, making them an essential part of modern security systems.
