Just started to use them. I ordered new business cards, door hangers, yard signs, and decals to ad to my trucks. I was surprised how many print shops that I was shopping for price had no clue of what a QR code was. I see a tremendous advantage to use them in this lazy, smart phone info seeking world. I have the code directed to my web page which is another thing today's society demands. It's great low cost advertising.
yeah but isn't your website already on the front of the business card? i guess it would help them get there right away on their phone though. i dunno i don't even have a website. i do have a free facebook page though for my business which is basically the same thing.
