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.
