I’ve used QR codes in the past and I have a lot of friends that are very high on them, but I’m with Google on this one. QR codes are too limiting and near field communication is the future. QR codes have 6-12 months self-life left in my opinion (or whenever Apple comes out with their new iPhone).
If you think about it, to use a QR code, someone must have a smart phone, know and recognize what a QR code is, download an app, align their phone just right and scan it in hopes that it’s something they’re interested in. With NFC, you simply tap your phone against the target and the information is beamed to your phone.
