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 bar codes 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 WLR8900 series scanners
extremely rugged since they have no moving parts. Wasp WLR8900 series
scanners are support PS/2 or USB keyboard interfaces and easily wedges
between the computer and keyboard. Barcode data is passed directly into
the keyboard buffer as if it had been typed in by hand by a data entry
operator.
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. The Wasp WLR8900 series scanners are extended distance scanners
with a depth of reading of up to one foot depending on the mil size of the
barcode. 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.
