I finally got round to designing my business card. I’m using Vistaprint just because I have used them before, and know what to expect. I also had a previous design for a personal card that I could use as a template. I uploaded my design as PDFs for both sides. Their upload of PNG for the reverse produced a blurred image even though there was no scaling. That was not impressive. My Business Card.
Useful hint: The QR code on the back points to a redirect page. It’s better to do this than have it point direct to the home page. If you change your mind over what you want to be seen by users of the code you can change it without having to have a new batch of cards printed.
