Bitly
Bitly approaches QR codes from the perspective of data. Because they are primarily a link-shortening service, their QR codes are inherently “dynamic.” This means you can change the destination URL behind the code even after it has been printed on a thousand flyers. Bitly’s customization options allow users to change the color of the code, add a logo in the center, and choose between a few frame styles. It is a robust system for marketers who prioritize click-through rates and geographical data over pixel-perfect design.
