Make a dynamic QR code, choose what it does, and download it for print
Open QR codes, choose Create QR Code, give the code a name and a destination, and save. The QR code links to a short URL that QRbolt redirects, so you can change the destination later without reprinting anything.


Use the download button on a code's card. A standard PNG suits screens and documents, the high resolution PNG suits most print, and the SVG is a vector file that stays sharp at any size, which is what a designer or printer usually wants.
Test a printed proof with two or three different phones before a big print run.
