The first commercial bar code was scanned in a grocery store in Ohio three decades ago. Since then, bar codes have become the most ubiquitous method for collecting information in the supply chain.

Laser scanners, which read 1D bar codes , are the most common. These devices read bar codes in conjunction with an oscillating mirror that automatically moves the beam back and forth across the bar code.

Imaging technology can also read 2D bar codes and direct part markings and is beginning to take a larger share of the market. Image systems capture an image of the bar code, much like a digital camera. Software is then used to decode the image.

Imaging technology is more tolerant of the conditions our customers face in an industrial setting. With an auto-focus feature, they can capture images, and in the future capture video, from a few inches away up to 30 or 40 feet away.

Regardless of scanning technology, bar code scanners are available in hand-held devices and fixed devices, which are used to automatically scan packages without human intervention. Fixed scanners are most commonly used as part of a conveyor solution.

Do you need a laser, CCD, or digital imager? Fixed-position or mobile? Should the scanner be integrated with a mobile computer or be a separate handheld unit? Cabled or wireless? What if you need to read 2D codes or capture signatures? Iteratonia has the answers, and the full line of products to meet these and other needs.
