Improving business logistics using barcode scanners

Posted by Jim Walker

The large and frequent orders on the Internet, and a large number of products available in retail stores, place more importance on barcode scanners in logistics than ever before. In this sense, it is imperative that distribution centers develop new applications to improve this process.

Barcode Scanners in logistics markets

  • At the most basic level, a traditional area scanner is combined with a laser scanner to read the code for fixed or slowly moving objects.
  • The best range consists of an image-based reading system with a linear camera, and it supports high-speed applications for reading bar codes from various sides.
  • The third level falls between these two extreme levels, and there are now many applications that rely on increasingly complex generations of laser scanners.

How Barcode Scanner helps in Improving Logistics

Bar code scanner Read code for strict control: Distribution centers need to carefully manage inventory, including purchasing, shipping, and detailed inventory management.

Laser barcode scanners provide high read speeds with high-quality printed barcodes when the label is not damaged, but the code is very difficult to read under less than ideal conditions.

Image-dependent barcode scanners, on the other hand, have limited their use in large distribution centers due to cost and complexity, but they can improve reading speeds so far.

Today, a new generation of image-based leaders is revolutionizing the market and set to offer adequate speed at prices equal to or below the laser alternatives.

The quality of the printed barcodes varies greatly depending on the number of packages dealt with, the printing technology, the shape of the label, the place of origin, and many other factors. Laser scanners cannot read incorrectly printed codes.

Some laser scanners attempt to solve this problem by combining multiple scan lines to reconstruct the corrupted code.

More powerful

With rapid growth, distribution centers need to manage more and more packages, not just assets and destinations. All this increases the need for higher efficiency and faster read speeds.

Distribution centers with barcode reading errors can use line-based scanners. These readers capture high-resolution images of the package surface containing line-by-line code as the beam progresses, similar to how a document scanner works. It then analyzes this image to find and interpret a valid symbol, regardless of its orientation or position within the package.

Image-based barcode scanners have several advantages over laser scanners in the logistics industry. Firstly, the images are valued at more than 1000 laser scanning lines, so image-based scanners are more valuable information for barcodes. This feature allows you to read code that has been properly degraded due to corruption, orientation, or distortion.

To compensate for code corruption and light reflections from the beam, the analysis software can reconstruct important data from the readable portion of the image.

Conclusion: Prepare for the future

The further integration of distributions will place significant pressure on the capacity of reading systems, while the diversity of origins and destinations will continue to increase. Most travelers seek to reduce the cost of investing in capital goods. They want to make a long-term investment to prevent the equipment they buy from becoming obsolete in the short term. In this environment, the long life of the image-based system is a huge advantage.

Therefore, the future belongs to image-based reading technology. By learning more about moving to this new technology, fulfilment centers can avoid slow readings by lowering profit margins.
