I'm hoping it's the way to go! I used:
http://www.qrstuff.com/
to get my QR code which has a link to my V-card (so you scan it with your phone and it adds name, phone number, company, e-mail and website so you just have to "save", rather than have to type it all in).
I coloured it to my company colours and popped it on the back of my business cards and on the
contact page of my website. I'm very chuffed with
how they turned out!
