I never knew that "Near" meant "Right on top"... =/

@adamc260 theoretically NFC is supposed to work at a distance, but it is a fairly weak connection therefore having them closer will give you the best results. Don't expect it to work from a further distance, chances are it will take forever to transfer data or it'll be too weak to connect.

when will this be activated?

[whtsurproblem111]

@Lostzilla847 it really depends on the developers and businesses and how they want to incorporate this technology.

I have a Samsung Nexus S with the NFC feature. My recent acquistion of a Galaxy S 2 does not unfortunately. So other than passing single object data from one handset to another, at the moment I see this as a limited technology.

I wanted to know is there a difference between non nfc s2 vs s2 in features,is there any features missing in the s2 with nfc. i heard s2 without nfc has better screen color is this true.

@adamc260 It doesn't have to be touching, but the standard says 20 cm at most. So about 7 inches or less. It's a really weak signal intentionally so that it's low power and secure so somebody has to be pretty much on top of you to do it.

Bluetooth is in the very crowded 2.4 GHz range, where as this is transmitting at 13 MHz.

@whtsurproblem111 I've been scanning tags from about 4cm away (vid on my channel) not sure what it's like phone2phone but should still work ok with a bit of distance.

NFC is not QR Codes. NFC is Near Field Communication, it allows you to either actively or passively transfer data of any kind, not specifically QR codes. The transfer rate, as you mentioned is indeed slow, but you could theoretically share large files across the it if you wanted to.
