If your printer asks you for the URI that generates the QR code, it is simply
https://tgz.bz/01/**"your GTIN with a preceding zero"**
So for example, if we take the Polytag 13-digit GTIN 5060919080055, the URI to generate the QR code would be https://tgz.bz/01/05060919080055 Note that the QR codes created by these URL’s will only scan if you are on a paid plan with Polytag (on the free plan you can scan our demo QR codes to see what the end result looks like).
When downloading one of your SVG (vector) files, or providing your URL to a printer, this is to print what we call Polytag QR codes (you may also here the term static, which means no variable data within the code). This means the QR code will be the same per each product (GTIN). Whereas with Polytag's unique-every-time QR codes, every individual instance of a product has its own unique QR code.
