Just wait for Apple to put it in the iPhone so they market the hell out of it and people start to care. It's kind of silly, but they're a large force in the industry and the feature will be available on every new handset they sell as opposed to a few models.
I feel like that's how it's been. Apple's driven the industry successfully. No one cared about front facing cameras til Facetime made it big. Heck we had front facing cameras in 2006 or so on the Nokia N-series phones.
NFC was such a big thing last year at the Nexus Launch but it took til summer for the wallet app to come out and even now it's useless. So the new Galaxy Nexus advertises NFC Bump and a lot of other things. Maybe that will take off? Who knows.
The funny thing is all that Paypass/Blink/RFID-based stuff hasn't taken off. I remember the Paypass card going around in 2007 or so on Citi. However, with my most recent updates, my Chase Freedom lost Blink and my Citi Dividend lost Paypass. So if anything this whole touch-based payment is not taking off. Given that the same terminals are used for RFID credit cards as NFC, I don't see how NFC is going to take off anywhere in the US.
As for NFC in Asia, is it really NFC? I see the subway cards used EVERYWHERE in Korea, Taiwan, and Hong Kong, but seriously a lot of people still pay in cash in Taiwan and Korea, even if 90% of the population has a subway card. Furthermore, it's a subway card, it's not a credit card. Credit cards are not as popular in Asia. I can swipe for everything in the US from something as small as a 99 cent bag of chips at 7-11 to a $2000 TV here, but I see it rarely used overseas still. For example, eating with friends we'll credit card roulette here or split credit cards... but I've always seen cash payments done with my cousins when they take me out.
So while you see a lot of RFID payment terminals in Asia, I don't know if that means they'll jump straight to credit card NFC payments. Otherwise all the worldwide phones like the SGS2 would've had NFC and there would've been some NFC payment service other than Google developed and already popular in Asia.
