It's well known in the security world that both NZ and Australian banks have some of the most lax card security in the world. This is the reason that New Zealand is now being hit by card scammers - it's becoming increasingly difficult to skim card details in Europe due to enhanced security measures in place. There are also numerous reported cases of European retailers now refusing to accept NZ or Australian credit cards due to the risk of fraud.
So what can we do? New Zealand banks should immediately be replacing all credit and EFTPOS cards with chip cards which offer a significantly higher level of security compared to existing magnetic stripe cards which are very easily cloned. PIN numbers should also be required on all credit card transactions as is the case in the UK and very soon all of Europe. Chip cards are not entirely foolproof however - there has been a case in the UK where EFTPOS terminals have been phyically altered to capture card details and send details via Bluetooth to capture equipment nearby due to a fundamental flaw in the architecture of the 3DES security for terminals that doesn't encrypt PIN numbers between the pinpad and the terminal.
So why don't NZ banks do something? Like everything banks do it's all about risk management. Replacing cards and upgrading infrastructure to replace mag stripe cards with chip cards costs money. Large amounts of money. It's obvious right now that these costs exceed the amount it costs backs to refund customers for fradulent transactions. Due to our lax security New Zealand is now turning into a prime target for scammers and skimming is a problem that is now going to become progressively worse until the tide turns and banks start taking security seriously.
So what can you do? Ensure that your credit card never leaves you sights.
* Hand over your card at a service station if they want to hold onto it when pumps are on prepay.
* Hand over your credit card at a cafe/restaurant for payment. Take the card to the counter yourself.
* Ask your bank what THEY are going to do to step up their security measures. In particular when THEY will be introducing chip cards for EFTPOS and credit cards issued by them. Remember YOU as a customer are in effect paying for fradulent transactions as its's simply part of their cost of doing business and reflected in the charges they pass on to you.
* Check your bank statements carefully. Report any suspcious transactions immediately.
* Be aware of any suspicious activity near ATM's.

In case anyone thinks Sbiddle is being alarmist, remember that EFTPOS transactions are extremely hard to dispute unless there's an apparent pattern of fraud.

Most interesting. I must admit a few times now whilst at the check out I have stopped when about to enter my pin number and turned to stare at the person behind in the queue who is peering over my shoulder.
Myself i always step back when the person in front is carrying out their transaction, but some really are intimidating whether they mean to be or not.

What banks issue Chip cards. ASB has just launched their Platinum card which has a chip but most retailers struggle to use it. Banks should make it compulsory - set a dead line so all equiptment and cards start getting upgraded.

RFID chips are more likely to be misused and abused and is a absolute violation of your private details when someone standing 100ft away can access your information, just like your passport you can use readers to see your cards details. Those chips have transmitters in them, even though the power is low as long as you can read the signal your home and away and yet another problem arises.
Frankly I'm opposed to what you said, without card protection sleeves your absolutely more vulnerable to fraud. There's other ways to protect yourself against fraud, surely the banks can adopt better systems than jumping onto unproven and unsafe technology.

Not sure if any of you remember but ANZ released a chip card quite some years ago but the take up was so bad and retailers didnt understand how to use it that it was pulled. I had one and it was kinda cool but a little too early for the market. You even got a USB card reader for home for secure web transaction. it was called the ZED card and had the ads with Brains from thunderbirds. ANZ Australia have released chip cards for the second time and I think those a re doing a bit better but it comes down to ease of use, cost and ultimately consumer choice.

How does all this affect the security of online credit card transactions, that simply involve the passing of the credit card number and expiry date? Will this become a deprecated activity?

Your do's and dont's are very sensible and good advice. Unfortunately the body of your logic is flawed. Have other country's banks completely eliminated fraud of this type? The criminals will always find a way around the security and the only way to prevent this is to stop using cards. By far the majority of card transactions are safe and if people follow your do's and dont's there is reduced risk.

Having been involved in the privacy and security industry for over 20 years, Can someone please EXPLAIN to me - HOW A CHIPPED CARD (RFID or not) offers better protection than what's available now?! The only reason to use chipped cards at present - the fraudsters, haven't bothered to figure a way around them - YET! In two years time, having a DNA reader at the bank terminal will be shown to be the best protection, because so many people are now getting stung with RFID frauds. It's not a hardware change that's needed, it's a political one! Stop the PC (political correctness) garbage, and give the offenders a penalty that discourages them. Stop blaming the poor innocent guy that owned and used his card as required and make the penalty for abusing the 'normal' persons trust, - HARSH!

Rubbish. The skimmers last time were caught forthwith and deported. These guys will hopefully have the same fate. ATM skimming is not an issue in NZ - this is the second instance only, and the media and banks react quickly. Please back up your assertions about NZ cards being refused. And are they refused becasue they are NZ, or just non-EU, or just non-Chip/PIN? How much did the Chip/PIN transition cost? How much of that 25% drop still remains? When I was in the EFTPOS game (early 90's) NZ had the toughest security going. The requirement for a PIN on unattended transactions, the PIN reader physical security, PIN reader session key requirements and so forth - the often painful security the banks insisted on all contributed to a fantastically secure system overall. Meanwhile in the USA they simply copped a higher fraud rate, and they still do. I agree - no matter what system is used, the basic laws of card transactions still always apply - don't let your card out of sight, don't ever disclose, write down or let anyone see your PIN (cover your hand when you enter it) and report card loss immediately. And if you see anything strange on an ATM then stay well clear.

Unfortunately in this country security actually means nothing to the banks. They won't put up proper security screens to protect their own staff, so do you think they're really going to be bothered by skimming or other such fraudulent activity? I don't.
It's my belief that changes to security will only start to occur when the banks insurers start saying they won't pay out unless decent security measures are implemented.

Don't Visa and MasterCard merchant agreements require the merchant to accept international Visa / MasterCard Credit Cards with no chips (i.e. a New Zealand Issued Visa being used in the UK?)

Retailers refusing to accept chip cards is just retailers being dumb, and is nothing to do with fraud in my experience. I travel a lot and never have an issue in UK & Europe with my non-chip-cards being accepted, although I occasionally have to remind retailers in the UK they *can* accept them. I'm not convinced that chip cards will do much to enhance ATM security, as it will just shift the problem (either to people skimming the chip, or to people with "legacy" cards being the one impacted, e.g. tourists.) I seem to recall a big announcement in 2005 by Visa APAC that all Visa cards (including NZ) would be EMV/Chip enabled by 2006 - that fell a bit flat! Interestingly, despite living off my credit cards and traveling to 3-4 countries a month, the only cases of card fraud I've had have been related to taxis.

I'm in the US at the moment. When I hand my card over here they simply swipe it through a machine. No PIN, no signing. Some retailers ask for ID with the card, but most don't bother.
How's that for card security?!

Your information "anti skimming devices had card skimming attachments fitted to scan the card details" is really helpful to protect our selves from becoming ATM fraud victims.. atmsecurity.com
