ABSTRACT:
A card reader operated in proximity to secured area control point including an operating system therein to provide multiple operating modes. The card reader is operable to provide access to a secured area by entry of an identification code, which is read by the card reader, or entered to the keyboard. The user will be granted access to the controlled area when the user access requested corresponds to the level of access provided by the identification codes presented. The card reader has a programming mode, to allow a station manager to program the reader for presenting a programming code. The card reader system also has a degraded mode of operation, which allows user access after power fail and reader restart. A keypad having an interchangeable faceplate is used for all three modes of operation to provide communication and programming with the reader by the system user. The faceplates are selected to provide labels only for the active keypad areas, and to prevent disclosure of proprietary programming and service information to unauthorized individuals.
