How a Bar Code Verifier Works

A bar code reader or scanner extracts the information that is optically encoded in a bar code symbol and converts it into computer-compatible digital data.

Hand Held Products provides a variety of handheld wand or pen scanners with the verifier that are designed to minimize scratching the symbol. When you place the wand on a bar code symbol and move it across the symbol, electro-optical techniques read the symbol. All wands contain a light emitting diode (either visible or infrared light) which illuminates the symbol.

The area of the symbol that is actually being scanned at any given time is referred to as the “spot” and is defined by an aperture. The spot size varies depending on which wand is used. The spot is formed by flooding the symbol with light. A tightly focused aperture collects the light. The light reflected from the spot is directed to a photodiode detector which generates a small current
