Hand Held Products 600, 800 How a Bar Code Verifier Works

6 - 6 Quick Check® 600/800 Series User’s Guide

The following table lists some characteristics of the nine bar code symbologies

decoded by the Quick Check 600/800 Verifier.

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
