Evidently I must be the only one.
Lets start with QR codes. I've used them, my missus (a nurse) has used them. They aren't rocket science once someone has explained how and are a lot easier than manually typing in web links.
As for NFC, I have a Galaxy Nexus and a bunch of NFC tags. When I get home, I tap the tag in the kitchen. Wifi is turned on, brightness turned up, etc. When I tap the tag on my bedside table, alarms are set, brightness set to low, media volume set to low...
Oh and the tags mean you don't even have to open an app. Putting your phone next to a poster is virtually zero effort. (Whilst QR codes basically have no extra cost to the advertiser)
You're restricting these technologies to advertising a little prematurely, and they do have a purpose, so what's the harm if they help even a few? I don't get the hate.
