مفاتيح RFID

An RFID key fob is a compact device that can be attached to a keychain, allowing users to electronically unlock doors. It employs radio frequency identification (RFID) technology to communicate with RFID readers. When the key fob is placed near a reader, it transmits a unique microchip signal, enabling the reader to grant access if the fob is recognized as valid. Commonly found in access control systems for office buildings, hotels, and parking garages, RFID key fobs come in both low frequency (LF) and high frequency (HF). These portable devices provide a convenient alternative to traditional keys and cards for managing access to buildings, vehicles, and other secure areas.
