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.
