Bar code scanners are designed to read imprinted bar / matrix code symbologies. Bar code scanners can be slot card scanners, fixed mount scanners, or hand-held scanners.
Fixed mount bar code scanners are designed to manually or mechanically read items passed by their scan windows. Unlike hand scanners, they are affixed to a single location.
Hand held bar code scanners are used typically as inventory or point of sale (POS) devices. These scanners are passed over bar codes manually to read data. They often have a gun or wand design.
