All necessary information for access verification is stored in a battery buffered
on-board memory and a Compact Flash (CF) memory card. This guarantees
autonomous access decisions and complete access registrations even if the
management host system is offline. The built in compact flash adapter provides
adequate storage capability for cardholders and events, simply by exchanging
the standard compact flash card with 64 MB by one with 128 MB, 256 MB,
512 MB or 1 GB capacity.
