He created and hosts a highly customized barcode quality seminar which has been presented to 100's of companies, reaching thousands of quality-concerned people, helping them to avoid barcode problems and manage barcode-related risk.

Eight Simple Barcode Mistakes

Just because these barcode mistakes are simple does not mean they are obvious—many of them are subtle—so subtle that some verifiers don’t detect them. Barcode mistakes fall into two broad categories: design errors and printing errors. Neither is more important than the other. Perfect printing cannot overcome flawed design, but neither can perfect design overcome…

The Expanding Use of Barcodes

It took over twenty years from the issuance of Bernard Silver and Norman Woodland’s patent for a printed barcode pattern (1952), for the grocery industry to recognize and adopt the technology (1973). It took another four years (1977) before scanners started appearing in grocery stores in any significant number–if about 200 store is considered a…

The short answer is any company with potential liability if a barcode does not perform as it should. That includes everybody who touches that barcode, from the graphics designer, the pre-press service, the…

Barcode Scanner Differences

Why do different barcode scanners behave differently? Even some scanners of the same brand and model behave differently. Why is this? Barcode scanners, like other devices, are manufactured to a specification, and every specification has a tolerance or margin of acceptable performance error. This is why even otherwise “identical” scanners of the same make and…
