In an interview, Apple Senior VP Phil Schiller said that Passbook alone does what most customers want and works without existing merchant payment systems.
I tend to agree with his statement on NFC. While it is a neat technology, an overwhelming majority of merchants have no NFC hardware (and probably don’t have plans to upgrade).
As for wireless charging, Schiller notes that the wireless charging systems still have to be plugged into the wall, so it’s not clear how much convenience they add. The widely-adopted USB cord, meanwhile, can charge in wall outlets, computers and even on airplanes, he said.
That makes sense as well. In order to use wireless charging, you need to plug in a wireless charging base station (and have one everywhere you might want to charge your phone).
