6.3 HOW ACCESS CONTROL WORKS
To illustrate how Access Control functions, we will use three simple Access Control System examples:
Figure 6.1: Example A
Bonnie’s Access Control Card is
programmed with Access Level
01 and Schedule 01. If she
presents her card to the reader
on Door 02 on Tuesday, August
3 at 3 p.m., she will gain access
to the room.
Figure 6.2: Example B
If Bonnie presents her card to the
reader on Door 02 on Saturday
or on a Holiday at 3 p.m., she will
be denied access.
Figure 6.3: Example C
If we change Bonnie’s Access
Level to 02 and she presents her
card to the reader on Door 02 on
Tuesday, August 3 at 3 p.m., she
will be denied access.
