Badge Reader Definition/Meaning:
A device designed to read information encoded into a small plastic
card. It is often part of a data collection system in which each operator can be
identified by the badge they present to the machine. It can also be used to
control access to areas associated with electrically operated door locks, and
when built into keyboards and other parts of information systems it can control
access to information.
The badge is usually of plastic, or paper laminated between plastic, and may
contain a photograph and other information in addition to what is encoded. The
encoding takes many forms, some of which are proprietary and complex to achieve
greater security. The most common form for data collection systems in an
industrial environment was originally me punched badge: there were five
standardized formats using the rectangular punched holes common to the 80-column
punched card. The punched badge reader is being superseded by devices dial sense
information encoded by printed marks or characters, by capacitive or magnetic
elements embedded within the card, or by magnetic recording on a strip of
material on the surface.
