Automatic identification: how to assign a barcode correctly
It is known that automatic data collection has long used barcoding, and it is a widespread practice in people's daily lives. A closer look at this technology is needed.
Why are barcodes necessary?
Using barcodes makes it possible to easily, quickly and accurately acquire and pass on information on various goods or objects. Most often barcodes are assigned to lines where information regarding them is required for inventories and monitoring transport: packaged foods, containers, furniture, cosmetics and many other things.
Nowadays in order to draw up a barcode there are several special symbol sets or 'languages', made up of various combination of stripes and gaps. Most frequently in Russia the EAN-13 format with the first numbers 460-469 and 793-799 is used on goods, and the ITF-14 format for transportation packaging.
How are barcodes applied?
There is a range of methods for applying barcodes: they can be printed on the packaging by its manufacturer, they can be printed on special sticky tape and then stuck on packaging, for example, as is done with goods sold by weight. Grocery shops often have barcode printers.
Who assigns barcodes?
It should be noted that automatic identification has a particularly individual character so each item of goods has its own barcode. The DiSAI international system, which has a presence in Russia, was set up to centrally allocate barcodes.
