Key Fobs allow you to access the building and various ammenties. The building entrances, elevator lobbies at each parking level, and ammenity rooms such as party room and gym are equipped with proximity fob readers. To unlock a door you simply hold your proximity fob within 5 inches of the card reader. The benefit of this system is its ease-of-use as well as its security features. Among other things, the system allows the property manager to add and delete entrants, thereby controlling who can and cannot enter the building.
