I think there's a lot more friction involved in interacting with a QR code: tapping a phone to a surface is a lot easier than opening the appropriate app and trying to focus (hard in low light) on the code.

But it's not like NFC based card would solve this problem, you should still give a permission (I think) if you want the contact to be added to your phonebook etc. I understand you have to put the card very close, 3-4 cm or so to the phone but otherwise it would be good way to troll or scam people... create a fake card and the name would be Your Mom, actually call to a friend/extremely expensive number... or things like that.

  NFC could easily be implemented so that permission isn't necessary, but even then tapping on one's screen (only the sender has to tap in the existing implementation of Android Beam) is much lower friction than scanning a QR code.

    swipe>unlock password> 123456 AppX>locate, open Permission?>Y/N Its not frictionless either way. NFC cannot be trusted. You need to aknoweldge Y/N prior to letting anything write data onto a phone. Too much risk otherwise.

      You don't need to location AppX, the Android Intent system (Android being the only consumer mobile platform with an NFC implementation at the moment) can respond to the data in the NFC tag and open the appropriate app. I'm not claiming it's frictionless, but just that there's less friction than a QR code.

The worst QR code implementation I've seen was at a quick-lube place. The QR code was on a banner inside the garage, but because the light from outside would wash out any camera, you had to get out of your car to scan it. Then all it did was open a web page telling you to text a number to get a coupon...
