Technologies are driving the world<\/strong> and significantly changing the ways of working in retail, warehouses, and logistics. Instead of manually recording data on paper, today we can encode all necessary information into a simple barcode.<\/strong> There are several options \u2013 so which type of code is worth using, and when? <\/span><\/p>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The first major breakthrough in automation came with the 1D barcode, which encodes information using black and white bars. We most commonly encounter it in the form of <\/span>EAN\/UPC codes,<\/b> and it can be found almost everywhere \u2013 on groceries, books, and courier labels.<\/span><\/p>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

          Under the pressure of the need for more data and connection to the digital world, we are globally moving<\/strong> towards 2D codes. This change also has an official form:<\/p>

          Sunrise 2027<\/strong><\/p>

          The GS1 organization, which standardizes barcodes, has launched an initiative requiring all point-of-sale (POS\/POC) systems to be capable of reading 2D codes<\/strong> by the end of 2027<\/strong>. This project is already being tested in over 48 countries covering 88% of the world\u2019s GDP. <\/p>

            GS1 does not plan to completely replace EAN\/GTIN \u2013 instead, it expands them through the GS1 Digital Link<\/strong> concept. This allows encoding the EAN into a URL that leads to a webpage with additional information (nutritional values, certificates, instructions, etc.) and enables tracking customer behavior statistics. Thus, the EAN does not disappear<\/strong> but transitions into a modern digital form.<\/strong> <\/p>

              The transition to 2D codes will not be abrupt \u2013 the next several years will be characterized by placing both 1D and 2D codes together<\/strong> on a single product. Gradual replacement is expected in sectors with higher demands<\/strong> \u2013 such as pharmaceuticals, automotive, or luxury goods, where this change may occur sooner. <\/p>

              Summary:<\/strong> 2D codes will not erase EAN but will take over its role in a more modern form \u2013 as a carrier of richer and interconnected data. The transition to them is necessary and accelerated by the \u201cSunrise 2027\u201d initiative, but a complete replacement of 1D barcodes will occur over the coming years and always in accordance with the investment and operational capabilities of individual sectors. <\/p>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
