Paying for the things you want in the blink of an eye. Sounds amazing, doesn’t it? You don’t sign, or PIN, or even touch. But who’s to say its you buying? How NFC back-end fraud detection must get smart!

You see, this speed carries one big penalty. Security. Not for the device, for you. The transaction is now so fast, it can’t be fraud-checked conventionally.

“Contactless” means just that. No contact from either side – counter or customer. There’ll be no alerts, no chance to stop a fraudster. Or is there?

No, it’s not the latest story about National Australia Bank’s recent system woes. This is something just as radical, but far more positive.

NAB has split from the other main street banks to embrace the social web in style. They’ve suddenly discovered Facebook, YouTube, Twitter and viral marketing. It had to come, but who'd have thought NAB?

Maybe it was a realisation that NAB’s professional reputation was in tatters, maybe just a change of marketing agency. Either way, NAB’s changed course. And its a course that could change the face of Australian banking.

I was an NCR IT field engineer. Every day, my boss would hand out repair tickets. These told us what IT system problems we had to sort out that day.

too busy to help you - stop worrying me. One guy had this trick. He’d keep all his old tickets. When the boss came to him, he’d draw in breath and shuffle the tickets, looking like he had a lot on.

The boss never gave the guy the urgent jobs. He’d just take the tickets he liked. He must have taught a lot of people that trick. I see them everywhere.

Keepers of the process, the emperors of the end office. The checkpoint Charlies.

You know, for me, the most frustrating thing in the world has got to be hindsight. And coming up with that great question or comment too late.

People will talk - its what makes us - well, us.

I’ve just attended the Manchester 2011 Information Security Leaders seminar. Inevitably, discussion turned to Facebook use in the office.

Part of the event was an open-mike panel featuring some of the great and the good of the security industry and a couple of leading industry security figures. And Facebook made them nervous.

Afterwards, the question I wished I’d had the forethought to ask came to me…

I can’t believe how fast this technology is developing. Everyone seems to be at it. Mobile is big and NFC seems to be flavour of 2011.

NFC- fastest way to empty your wallet so far. NFC uses your mobile phone to part you from your hard-earned money instantly. You don’t have to touch, key in or sign anything. Just wave your phone about.

Well, I say you – but what I really mean is it doesn’t necessarily have to be you, just anyone who happens to have your phone.

And I’m really, really not happy about that.
