RFID FOBs (Radio Frequency Identification Key Fobs) are compact, wireless access devices commonly used in residential buildings, commercial spaces, and gated communities. They operate by transmitting a unique radio signal to an RFID reader, allowing authorized users to gain secure access without the need for physical keys or contact-based systems.

RFID FOBs are widely preferred for their convenience, security, and reliability. They are often used for entry doors, parking garages, elevators, and private amenities. With advancements in access control technology, RFID systems provide a more efficient and tamper-resistant way to manage who comes and goes—ensuring both safety and ease of use.
