I'm looking forward to seeing NFC being developed further. I'd also like to see it done with no-app required. Estimotes and iBeacons have made waves in this area; and are very developer friendly. The quick saturation of QR codes (in spite of their lack of use) has been a testament to the fact that customers want information digitally, on-demand, and "to-go". However, QR codes are antiquated. No smart-phone has EVER come equipped with a native QR code reader. AND, QR code inquiries aren't a reciprocal exchange; ie: the customer gets information, but the dealer doesn't get theirs. Dealers are better off usings short URL's to divert to convertible landing pages.
