Finished bar code scanners from ID TECH are completely housed computer peripherals that simply plug into a PC or laptop. These readers can sit on a countertop, be attached to a vertical surface with Velcro, or mounted with screws. Others are hand held and, in some cases, contactless. Some units are even sealed and/or ruggedized for use out of doors.
OEM modules from ID TECH are unhoused readers known as "rails" that can be designed into larger products requiring bar code and/or magnetic stripe capabilities. These products have a range of mounting options and interface choices.
