Not beyond the realms of what could be placed on a business card, a lot cheaper to make and certainly more useful for most phone users.
On the other hand, the NFC card is a lot more attractive looking and has an extra "wow" factor. Of course, it would be useless to me as my phone doesn't have NFC, so I would be left keying the contact details into my phone by hand.

I'm not saying for the basic info a VCARD QR Code won't work, but for more info it breaks down.
