Many switched on brand owners including SME businesses are starting to interact with packaging using free barcode reader apps on smart phones. We have blogged on this subject previously. By far the most popular format is the QR barcode format, pictured above. If you scan this one it directs you to a website (its interesting, try it!) . At Mercian Labels we have the ability to offer both fixed and variable 2D QR barcode labels to our customers, and can set this up for you on your artwork. If you are interested, then please contact us to discuss what you wish to achieve.
