Smaller World (Bar Code Inspection)

A certain degree of automation is integral to ensuring bar code parameters are met, and different approaches to this capability are evident in current online and off-line verification offerings.

According to Spitz, Webscan's off-line TruCheck unit was developed in response to the company's online customers, who saw the reliability of online measurements, but wanted to eliminate wands and guns in applications that did not warrant online equipment. Its laser automatically moves from top to bottom through a bar code, collecting the 10 ANSI-recommended scans. Operators place the sample under the laser and touch a button, allowing automatic control for consistent results.
