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.
Computer mice and pointing devices are used to control the screen-based movement of a cursor or icon on a visual computer. This category includes mice, trackballs, and touch pads.
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.
Industrial keyboards are peripheral hardware devices that include alphanumeric keys, electromechanical buttons, or sensors that users press to interface with a computer.
