Barcodes are forgiving of a wide range of inaccuracies. The experiential evidence alone validates that: how many times in recent memory have you encountered a barcode that did not scan quickly—or [...]
Barcode verifiers are designed to be reliable, which means accurate and repeatable. When they are not, eroded confidence creates an emergency with an uncertain path to resolution. One of the most [...]
It seems obvious until you think about it. What is not barcode quality? Obviously, it is a barcode that does not scan–and yet, as we have recently written, a barcode that scans perfectly [...]
The Scan Reflectance Profile (SRP) is a primary tool for diagnosing barcode problems. It graphically represents the entire barcode and its scanning performance. This is the most important tool [...]
Today there are 3 different types of barcode scanners. The broad categories are: Laser CCD Camera Technically, there is a 4th type—the wand or pen scanner but this is old technology and few are [...]
Barcode scanning problems fall into two categories: the barcode does not scan at all, or it scans inconsistently. Non-scanning barcodes are the hardest to diagnose since the verifier is not [...]
We have made the case in previous articles that barcode verification is risk management. We stand by that truism, but barcode verification is so much more than just risk management. That is just [...]
In some aspects, 2D barcodes are very different from 1D barcodes. Optimizing them for best performance is almost a completely different subject—but there are a few similarities. In a 1D barcode, [...]
Once the barcode on your product leaves your control, it could encounter a wide variety of scanners. They could be lasers, linear CCD arrays, area CCD arrays, camera-based and maybe even some old [...]
Where did ISO15416 for linear barcodes come from? Or ISO15415 for 2D symbols? What is the process that culminates in the development of an international standard? It is a fascinating story that [...]
