People already talk hesitantly about having all their contacts and email on their cell phones; how's it going to be with all kinds of payments, key access codes, etc. on the one device as well? And I don't like the idea of charges being taken out of thin air from my wallet and bank accounts. It's giving too much control away for a little convenience.

Please stop worrying about big brother watching what you?re doing. For one simple reason? no one cares. The worst you?ll see is some targeted ads. I?m not worried about security either, my phone already has bank account login info on it and wi-fi/bluetooth turned on. Having a wireless technology that only works within inches doesn?t seem like an added risk.

What I?m worried about is this ?but beyond security concerns I wonder if I'll have to sleep on the porch in the event that my battery dies before coming home.? Before coming home? If your battery dies you?ll be locked out of your car, forget starting it and driving home.

Well, in prehistoric times people used keys to get into their car. And forget it if you don't charge your iPad and have Comcast! You won't be able to change the channels on your TV either. Just ask the "Glee Lady" in the X-Finity commercials. She says, "I can change the channels on my TV right from my iPad"! Luddites such as myself have to make do with the 10 dollar remote that came with the TV.

You will be sporting enough to let us know if your identity ever gets stolen, won't you?

I hope you won't be selfish enough to deny us the opportunity of rubbing your nose in this post.

Octopus in Hong Kong is 100% anonymous unless, like me, you CHOOSE to register it with your BANK so you can get the auto top up. Banks have privacy laws and having an Octopus doesn't mean they hold any more info about me anyway.

It records every transaction. I think this is an advantage for financial reasons. It doesn't record exactly what I bought, only the time, vendor and amount. Nor does it record it was me who bought something; only that the card was used.

I must admit I am very worried about the state knocking on my door in the middle of the night saying, "Hey, we noticed your card was used for a lot more buses this week, and what's with all the stuff at 7 / 11 and McDonald's - the card should be used more at the supermarket - it's healthier". Very scary no ?

I also have a smart card to get into the university offices which I am very pleased about as they are much easier than keys. This could be used to track my position but it's hardly a crime to spend 11 hours at work each day.

Some ppl here are paranoid. Too much TV. And others are just plain stupid and let Facebook and Twitter track their every movement - "hey, I'm not at home, come rob me".

With everything, there is a balance.

As relative as using antivirus on a notebook in a glass house. Oppose to being in a lead box with no internet. Pick your horror?

I forgot to mention - my Yamaha also has nfc. It has a chip in the key that acts with the immobiliser so only the chipped key can start the motorcycle.

So that's 3 nfc devices that I use every day with no issues at all.

I think the suggestion that there will be one for everything is misleading and dumb. I already have 3 in daily use.

haha, i'll let you know. My point wasn't that this was perfectly safe, i just don't see how it's any worse than the other wireless technologies that already work on my phone. neither do i understand how taking my phone out of my pocket is supposed to be that much easier than taking out my wallet. And until i can carry my driver's license in my phone, i'm bringing my wallet.

People always freak out about security on new technologies. Technology had absolutely nothing to do with the d-bag who stole my GPS outa my car (in my garage) last month.

My biggest concern is having all your eggs in one basket (for basket read smartphone) The flat battery is just one way of getting stuffed. How many phones get dropped, lost or, worst of all, stolen. If NFC takes off phone theft is likely to become a big issue.

High quality smartphone security software like that at http://loky.me takes on a much more important role.

Why bother with carrying the device. They should implant the chip into a part of your body that regularly make contact, like your ***. As soon as you sit down, caching, $5 debited. When the boss tells you to get your *** outa here. Simply press your posterior against the door handle. When the bank manager tells you you're an asswhole, time to curb the spending spree.

The problem is people don't understand Big Brother until it's too late. All these new technologies feels good to you all now. It's just to help you get comfortable for the RFID chip which will be implemented into your body. Yes, you will be tracked. No, you can't escape. Your government is always finding new ways and laws to take away every bit of freedom you have.

Once you realize it, you will want to fight back like people did in the '60s and '70s. People are too comfortable now. It will be much easier to control you to the point you can't every fight back, becoming a modern day slave.

Research the RFID chip, make a true decision on your life.

9/11 = Unlawful Airport Xray Scanning all in the name of 'Terrorism' propaganda to keep US citizens in fear. Airport Xray Scanning, if the tech existed, wouldn't have ever went down in the '70s. We aren't criminals.....yet

See how easy people are in today's time to accept such nonsense?:

Think before you act

its ease of use, increasing convenience rather than enabling something new.............but my question is what is the global method of authentication.......suppose ur nfc device gets stolen.........
