Introduction

Barcoding is the most common Automated Data Collection (ADC)

technology providing timely, error-free information that can be used to

increase productivity, accuracy, and efficiency in the workplace. Virtually

every type of industry is using barcodes to replace keyboard data entry.

Studies have shown that a proficient data entry operator will make one

error for every 300 characters that are manually entered. The error rate

using barcodes is almost negligible and can be error-free using barcode

symbologies with the check digit enabled.

The Wasp Charged Coupled Device (CCD) technology is a technique

whereby a barcode is photographed, digitized, and electronically sampled

by built-in photodetectors. The detectors process the measurement of

every bar and space using the number of adjacent photodetectors which

contrast a black mark and a white space. Wasp WCS3900 Series Scanners

are extremely rugged since they have no moving parts. WCS3900 Series

Scanners plug into your PC’s USB or PS/2 port. As you scan a barcode,

the barcode value is automatically displayed in your application (eg. an

Excel cell, inventory application, etc.) where the blinking curser is, just as

if it had been typed on the keyboard.

Of all the hand held barcode scanning devices on the market, the CCD

reader is the easiest to use and most cost effective for the typical business

user. To activate the scanner, the user simply points the scanning aperture

towards the barcode, pulls the trigger, and aims the red LED beam across

the barcode. This scanner will work at a range of contact up to 1.5” away

from the barcode.
