RFIDK Access Control
There are a number of applications for RFID being developed for access control. In its most common form, RFID access for personnel may simply be the inclusion of an RFID tag in the identification badge of the worker. RFID has made inroads into this area that was originally dominated by the magnetic stripe badge. RFID applications for personnel access typically use low frequency, 125KHz, systems for the badge detection, and 13.56MHz for high secure requirement.
RFID badges can be used to control access in particular areas, for timekeeping, or other applications. For example, there are two popular medical applications that move into the higher frequency domain where the application is used to determine the location of either medical staff or wandering patients.
Access Control is a system which enables an authority to control access to areas in a given physical facility. An access control point, which can be a door, turnstile a parking gate an elevator or any other physical barrier where granting access can be controlled using RFID technology.
Data security is generally very high using RFID technology. It also reduces the possibility of duplicating credentials. Secure or proprietary communication protocols can also be used to further enhance security.
RFID based Access Control reader usually does not make an access decision but sends a card number to an Access Control panel that verifies the number against an access list. Generally, only entry is controlled and exit is uncontrolled. In cases where exit also has to be controlled a second reader is used on the opposite side of the door. The typical RFID tag is RFID based contactless smart card a key fob a wristband or a smartphone sticker.
RFID based Access Control Systems are typically used for Enterprise Access, Car Park Access, Access to Gyms or Swimming Areas, Event Access, Library Access or Access to Hotel Rooms.
