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 [...]
When I met Jeff several years ago, he was a work in progress—and so was Barcode Test. His very life was an expression of his non-conformity. On the other hand, I had about 35 years of barcode [...]
Barcodes and laminates are like an arranged marriage. There is little natural initial affinity for each other but someone else has decided they will be together. With effort and adjustments, it [...]
Statistics about barcode use, and in particular, barcode problems are difficult to obtain. Some of the information we have been able to gather is a bit out of date. However, we feel confident [...]
We have opined about the importance of barcode quality from a business perspective. What about the perspective of nations, economies and even humankind? If eye rolls were audible, I can imagine [...]
There are many mistakes one can make with the Unique Device Identification (UDI) barcode, but there is one that we see more often than others in the lab at Barcode Test. The simple rule that is [...]
