![]() GS1 has accepted two main standards – UPC and EAN13 – to be used in the purchasing and retail industry. Firstly used for designating a pack of chewing gums, they now are exploited everywhere. These linear markers, some of them numerical, some – alpha-numerical, are the oldest ones. To begin with the world-wide known zebra –stripped barcodes. To put it bluntly – barcodes are not only 1D and 2D – they can be 3D as well. Actually I made a little mistake – they are not only labels – there can also be forms and shapes, engraved or applied to certain surface. It is beyond shadow of doubt that these encoding labels ease our existence greatly. As I said in one of my previous articles, barcodes are all around us.
