Keyboard-wedge scanners
Keyboard-wedge scanners are connected between the computer and the keyboard sending data to the computer. The advantage with this system is that it does not require any special programming or software for basic functions. However using the programmable features it can be configured for many different kinds of data. Keyboard wedge scanners are very cheap to implement for data punching and retrieval.

Bar-code scanners:-The scanners use either of the two technologies Laser or CCD for reading bar codes. We are all familiar with laser beams which have been in use for many years. CCD or charged coupled device scanners take a digital photo of the bar code which is then read. CCD scanners typically work from smaller distance of a few inches while laser scanners can read from longer devices.
