A card is a physical credential carried by a user, such as a
proximity card, magnetic stripe card, or smart card. It has a number printed on
its surface, such as “789” or “00789.”
A user presents his or her card to a card reader — or “swipes” it
— to enter a door. The card reader reads the card and sends the data to a
control panel, which processes the request.
The card reader flashes green when a valid card is presented, and
the door unlocks. If the card is rejected, the card reader flashes red and the
door remains locked.
Cards are displayed in alpha-numeric order in the Card Bank, with
numeric identifiers listed before alphabetic identifiers.

NOTE: For card readers without indicator lights, a valid card will
still cause the door to unlock; there is just no green light to indicate
success or red light to indicate failure. |
