1. An apparatus for controlling access into an area to, comprising:

  • a server including server memory and a server data collection device configured to collect identification data assigned to an authorized person;

    a local access unit associated with an entrance to the area and including local memory, a local processor, a primary local biometric parameter sensing device, at least one secondary local biometric parameter sensing device, a local data collection device, and an access control device; and

    a communication channel for downloading the identification data from the server to the local access unit, wherein said local processor is operative to recognize an authorized user by comparing primary biometric parameter data of a person proximate the entrance collected by said local primary biometric parameter sensing device with primary biometric parameter data stored in said local memory, and to grant access to the area by operating said access control device if the primary biometric parameter data collected by said local primary biometric parameter sensing device and the primary biometric parameter data stored in said local memory correspond, wherein said local processor is operative to collect secondary biometric parameter data through said at least one local secondary biometric parameter sensing device when the primary biometric parameter data collected by the local primary biometric parameter sensing device and the primary biometric parameter data stored in the local memory do not correspond, and to grant access to the area by operating said access control device when the secondary biometric parameter data of an authorized person is entered if the secondary biometric parameter data collected by said at least one local secondary biometric parameter sensing device and the secondary biometric parameter data stored in said local memory correspond, and wherein said local processor is operative to prompt the user to provide additional biometric parameter data to the local primary biometric parameter sensing device and to store the additional biometric parameter data collected by said local primary biometric parameter sensing device in correspondence with the primary biometric parameter data stored in said local memory when the secondary biometric parameter data collected by the at least one local secondary biometric parameter sensing device and the secondary biometric parameter data stored in said local memory correspond.
