The BIS central cardholder management functionality allows corporate security
operators to centrally create, update, and delete cardholders and assign and
withdraw authorizations. With BIS 4.4, the operator is further equipped to centrally
monitor all access events and alarms from every connected site, such as across the
full network of stations of an underground public transport system. It is also a
perfect solution for global manufacturing industries or energy and oil enterprises,
which typically operate from geographically spread sites.

BIS 4.4 ensures that all multi-site cardholder information and access authorizations
are created on a central server but also replicated on all connected site servers.
This ensures that the same cardholder information is available in every location. All
access events from connected sites are also replicated back to the central server
for central monitoring.

BIS ensures continuous operation with its three-layer architecture. The purpose of
the third layer, the Master Access Controller (MAC) is to manage scenarios across
multiple Access Modular Controllers (AMCs) without the need for management

BIS 4.4 further enhances this third layer with a redundant Master Access Control
server, so that even in the event of a host system failure, central security operation
can continue. Also, in the unlikely event of a server failure, a redundant server can
take over operations, communicating with all local AMCs. This ensures that
authorized personnel have seamless, uninterrupted access in the event of a MAC
failure, but also that centralized security personnel continue to maintain full access

This increased resilience particularly benefits distributed systems, systems in
critical infrastructure, or manufacturing plants which require full 24/7 functionality
such as those typically found in large, global enterprises with many different sites
spread across several different regions.

Alongside the increased system availability delivered by BIS 4.4, the new software
version also ensures more efficient licensing management. As all cardholder
information and access authorizations are stored and maintained on a central
server, and can be replicated to all connected local site servers, data is
streamlined, eliminating the duplication of information ensuring optimal license
requirement estimations.

In addition to the 12 languages that the BIS user interface already supports, BIS 4.4
provides extended global support with an Arabic Operator User Interface for users
in the Middle East.
