The Evolution of Barcode Scanners: From Linear to 2D Imaging

Barcode Scanners

Barcode technology has gained high importance in the world of data management and modern logistics. Barcoding involves a way to encode data in an attractive visual pattern, such as geometric shapes and parallel lines. The imaging device or scanner interprets the patterns that present product details, tracking codes and other information. These details   are essential to manage, identify, and track your assets. However, barcode scanners have evolved over the years. Earlier, there were only linear or 1D barcodes for business. But, modern barcoding systems have a highly advanced design and provide better results.

Know About Linear Barcode Scanners

The idea of using barcodes could be dated back to the 20th century. Bernard Silver and Joseph Woodland were the first to invent the barcode scanner. Barcodes were used for the first time to develop a Universal Product Code. The UPC comprises some parallel lines that transformed the retail sector. It provides a standardized process to encode product details.

With a 1-dimensional barcode scanner, data was encoded in horizontal arrangements with different spacings and widths. Over time, there has been an innovation of Automatic Identification and Data Capture technology. The Evolution of Barcode Scanners: From Linear to 2D Imaging

Several businesses in the logistics and retail sectors started using linear barcodes to manage supply chains and track inventory. They used barcodes for automating checkout procedures and minimizing the effort of data entry. Logistics businesses also applied barcodes to deal with pallets and shipping labels.

But, linear barcode scanners have some demerits because they can store only a limited amount of data. Moreover, they are not efficient at capturing intricate data structures. Data correction capabilities are also limited, and there is a risk of data loss in case of disrupted barcode images.

Transitioning To 2d Barcode Scanners

2D barcode scanning technology helps with a large amount of data encoding in a versatile and compact format. 2D barcodes use 2-dimensional patterns of dots and squares to save data. The data storage capacity is more than that of linear barcode scanners. Modern scanners have a built-in error correction feature, and 2D barcodes withstand challenging environments.

Laser And Other Technologies For Scanning

The scanner for interpreting barcode information relies on lasers for data reading. In linear barcoding machines, the system determines the light that reflects off the barcode. It is essential to calibrate the scanner to read the particular type of symbology. However, with 2D barcodes, you will find a more sophisticated image-based scanner.

The scanners can process complicated encoded data in your 2D barcodes. Thus, if you need to deal with a large quantity of information, you can use these scanners.

Future Trends In The World Of Barcoding

Barcode scanners in the future will have stronger security features to prevent tampering and counterfeiting. You can integrate digital signatures and encryption algorithms into your barcode systems. There will be anti-counterfeiting features like invisible ink. We’re not seeing advanced solutions like ScanAvenger take the market by storm as barcode technology continues to expand.

To conclude, barcode scanners are useful for various industries, from manufacturing to transportation.
