Access Control
It is process allowing or
disallowing the access to a particular person to entity. For
example a software which is allowed to be accessed by only
limited number of persons.
A Conference room where only
some entities are allowed to be inside the room. We can use
Bar code technology to implement this control. A bar code is
a series of alternating dark and light stripes that are read
by an optical scanner. The organization and width of the
lines is determined by the bar code protocol selected.
In Electronics Terms, we have
many Electronics Security Systems like Electronics Alarm
Systems.
