Matt Engle's Industrial ID and Logistics Blog

First, you should be wary about what I tell you because I’d say just about anything to get a sale. : ) On the other hand, I do have some redeeming qualities and one of them is technical knowledge of industrial and logistics ID traceability technology and applications. I’ve been working in the ID industry for over seven years and have helped customers across many vertical industries solve their toughest barcode reading applications. My electrical engineering and MBA degrees are a great combination that has helped me balance between understanding the technical details and determining when it’s time to stop over analyzing and just get the job done. I hope you find something useful from what I have to say.

Laser scanners struggle to read poor quality barcodes in high speed logistics applications

Traditional laser scanners can only provide high read rates with good-quality printed barcodes when labels are undamaged. But barcode quality can vary dramatically depending on the amount that the package is handled, the printing technology, label geometry, point of origin and a host of other factors. Poor contrast, for example, may not provide enough difference between a printed and unprinted line to get an accurate read.

Because a laser scanner attempts to decipher the code along a single laser line, ambient light or specular reflections may also reduce the laser scanner’s ability to read the code successfully. Some laser scanners attempt to solve this issue by “stitching” multiple scan lines together to reconstruct a damaged barcode. This method works well in some cases, but not when damage is severe. Area-array image-based readers, however, take snapshots of the codes, like digital cameras, and use advanced decoding algorithms to decipher what’s captured in the image. Imager algorithms rarely fail, reading codes of all levels of damage and orientation and achieving six sigma read rates.

Have I convinced you to look at DataMan logistics readers as your new alternative to struggling laser scanners? If not, keep reading this blog and our website!
