    Proximity fobs

    Proximity fobs, also known as proximity tokens, are small electronic devices that allow for keyless entry into a system used in access control. They communicate wireless signals that are received by a sensor to allow predetermined commands such as lock and unlock to occur based on presence. Proximity fobs are part of the contactless card technologies and are used for access control, time and attendance, and other applications. They are available in various designs for operation in the UHF, HF, and NFC frequency bands. Proximity fobs typically have a read range of up to 50cm, which is the main difference from contactless smartcards with a range of 2 to 10cm.

  • RFID key fob

    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.
