NFC has quietly broken thru...elsewhere... while we are all waiting for the second coming of OTIV... if you did not invest in NXPI six bucks ago you missed the first ship. Look it over and have a prosperous 2013 !
True about waiting for the 2nd wave. There is really no alternative to NFC.
Believe catalyst will be when Apple puts it in the Iphone alternatively just keeping on growing slowly until momentum makes it roll.
OTIV seems more risky than NXP, but they are sitting on patents and is rather inexpensive - in my view.
