Access Control Systems Proximity Cards
Proximity cards use Radio Frequency Identification (RFID), to read a card or tag without requiring any physical contact between the card and the reading device. With proximity readers there is no physical wear and tear on the card or the reading device. No inserting of a card into a reader slot or swiping of a card through a reader slot is required. The card is simply held up to a reader, within the reader's detection range.
Benefits of Proximity Access Control
One of the many benefits of proximity access control is that you have no physical contact between the card and the reading device. With proximity access control systems you have very little maintenance costs associated with proximity card systems. Another benefit is the ease of use associated with the card. The card just has to be held near the reader to access an area. In some cases instead of a card a key-fob could be used and just attached to a lanyard or car keys for ease of access. The final benefit is the proximity cards are very difficult to duplicate because of the need for the microchip, knowledge of radio technology, and the software needed to implement the protocol.
