Northern Computers' KP-10 and KP-11 keypads may be used to provide access control security where no card is used, or in the case of the KP-10 used in conjunction with a card as a PIN (Personal Identification Number) for even greater security.

The unsurpassed ability of the KP-10 and KP-11 to withstand almost any environment enables the keypads to be installed in extreme climate conditions. At the same time the aesthetic appearance allows the keypad to be used in the nicest office.
