In order to print Polytag unique-every-time QR codes on behalf of brands, Printers must connect to the Polytag technology stack. This is to request the URLs from Polytag, each one containing the GTIN (barcode) and a unique serial number. The main method of doing this is by authenticating onto the Polytag Printer API (see details here), but for smaller trials and testing Polytag has a Printer Portal where Printers can download csv or xml files in two simple steps. In both cases, please get in touch with us! We can set up your account in minutes, grant you access to the brands’ products you want to print unique-every-time QR codes for, and off we go!
