    I just recently purchased the Nexus S for the Mrs. What exactly is a NFC tag and how does it work? Thanks for the help...

    It is a new technology that I do not believe is in use yet. Some of the things it is believed to do is maintain account data for thinks like credit cards and drivers licenses. Once loaded, you should be able to wave your phone in front of a point of sale device to pay for things. I believe Bank of America will be doing some testing with this later this year. Not sure which retailer will step up first to accept NFC though.

    I am getting my Nexus S 4G today and this is something that I will definitely not be using. I feel the security risk is too great. Does anybody else feel this way?

    what security risk? its a near field device. most tags work upto 1-2 inches away :)

    I actually ordered few blank tags to play with them

    This seems amazing to me. NFC Task Launcher App. You can buy tags for about $1 and make your own NFC tags. The possibilities are unlimited. Be sure to check out video! :)

    Thats what I did. Got few tags - found a NY place that sells them for around $2.50 so I got few to play with. App works great and there is alot of potential for NFC

    Let me clarify this. I will not be using it for purchases. (CC or debit card)

    I use cash for just about everything except online purchases and travel, including purchasing fuel.

    Very cool stuff here, can you need a separate programmer for the NFC tags or can the Nexus read/write?

    nexus does both read and write

    You can use it to swipe a tag (that you create) to toggle settings on your phone on and off. Above is what's available in the app today, tomorrow is only limited by ones imagination. You choose what you swipe. :D

    Oh I cannot wait to get my Nexus now and slap these tags all over. I always forget to silence my phone at work and this is going to save my job :p

    For people concerned about payment security, there are a few things you might be happy to learn:
    • It is PIN protected
    • The phone has a 'secure element', a chip that prevents theft, copying and tampering.
    • NFC is off when the screen is turned off
    • There are a variety of other security features that I don't understand.

    Security risk?

    Question do you give the wait staff your credit card when you eat out?

    Sometimes. I even go so far as to give clerks my checking account #, my DL#, my DOB, my home address, and my phone # when I write checks.

    My phone has randomly told me that it collected a tag twice so far. I have no idea what they were or where they're saved though

    I just got the phone, haven't done the NFC part, but I saw one of the apps called tags, in the app drawer. Have you looked there? Just curious now, but I went there and it briefly described it there.

    I would definitely recommend going through the links already posted.

    The potential for NFC is very good, perhaps somewhat parallel to Bar coding conventions (with the added advantage that the phone can read nfc without any specific doing from your part).

    I usually keep mine turned off, every time I get home and put my wallet and phone in the same place, the phone reads the public transportation tag located in the little card, for passing through station entrances.

    Plus there is no downside to it. No critical battery usage, no slowing down or bogging of the phone, worse case scenario, you never use nfc. Best case, you get some pretty cool use for it.
