I use an application that detects where I am and turns things off and on as required. Much better than waving your phone at a sticker.

Care to share which app?

Great idea, though I hope there reading this and start selling NFC proof wallet holders for them. What with all these NFC pass's for this and that and now credit cards, you would think somebody would sell proper protective wallets for them to prevent the details being read by passers by and the like (there be kit that can read them from across the street for a while now, its radio based after all). Still, I'm impress…

There is already plastic sleeves [1] with the same effect. The primary goal is to prevent interferences between all the NFC cards you'll have in your wallet (Yes, that's not a problem to have in the US for a few more years)

I think there's a lot more friction involved in interacting with a QR code: tapping a phone to a surface is a lot easier than opening the appropriate app and trying to focus (hard in low light) on the code.

But it's not like NFC based card would solve this problem, you should still give a permission (I think) if you want the contact to be added to your phonebook etc. I understand you have to put the card very close, 3-4 cm or so to the phone but otherwise it would be good way to troll or scam people... create a fake card and the name would be Your Mom, actually call to a friend/extremely expensive number... or things li…

NFC could easily be implemented so that permission isn't necessary, but even then tapping on one's screen (only the sender has to tap in the existing implementation of Android Beam) is much lower friction than scanning a QR code.

For reference, here's a QR code with a three line postal address, email address and mobile number: http://www.moongate.ro/products/qr_code-vcard/serve_card?c=K... Not beyond the realms of what could be placed on a business card, a lot cheaper to make and certainly more useful for most phone users. On the other hand, the NFC card is a lot more attractive looking and has an extra "wow" factor. Of course, it would be us…

Now add in PGP key sigs (or the entire public key), website, SSL key sigs, bitcoin address, and other information I haven't thought of yet, oh, and wrap all of that inside a VCARD, it becomes quite large quite quickly. I'm not saying for the basic info a VCARD QR Code won't work, but for more info it breaks down.

Wikipedia has some more information on it, but for realistically printable QR codes (version 10), you can probably store about a hundred bytes.

Alternatively you could use Video QR: http://stephendnicholas.com/archives/310 ;)

One of the primary features of NFC is the requirement that you be near (within inches of) the NFC tag in order for it to work. One useful application I've seen for this is a custom NFC tag someone placed in a homemade docking station to activate their phone's dock mode. Another was used in a homemade Gameklip[0]-type device to activate bluetooth and connect with the controller. [0] http://thegameklip.com/

And what happens when they're hidden in a perfectly ordinary desk blotter in a hotel room in Silicon Valley?

You've got the first act to a corporate espionage story.

Apparently the NFC opens a link to a QR code.

Ha very funny. My first thought was 'this sounds awfully a lot like a QR code'.

Also, as an iPhone user I feel NFC is not used nearly enough. Maybe Android users feel differently but until NFC is brought to the iphone I just dont see this being that useful.

I think NFC is great for things like payment. I actually used it for the first time in a new AMEX credit card that I got by just being able to tap the card on the register. It would be even cooler if someone would make it widely adopted on phones now. I'm sure it's just a matter of time.

swipe>unlock password> 123456 AppX>locate, open Permission?>Y/N

Its not frictionless either way. NFC cannot be trusted. You need to aknoweldge Y/N prior to letting anything write data onto a phone. Too much risk otherwise.
