I agree. On a business card that real estate is precious, and for a typical URL the time/hassle difference between typing and using a QR code is tiny. The only exception I can think of is if you or your division had its own page buried deep within the larger company’s site, so you put the short company url on the front and a QR code (with the long url below it) on the back, but I don’t think I’ve ever come across that.
I could see QR codes on larger mailers, but still it only really makes sense to me if it is linking to a sub page on the site, not a home page. We recently got a mailer with a QR code from a printing company that was offering a promotional discount, but instead of going to a page about the promotion the QR code just took me to the home page. I found it rather lame.
