Police say a form of credit card skimming which takes money off high-tech credit cards will come to New Zealand and people should be prepared for it.
Wave-to-pay cards can store up to $80 in cash and can be used to buy petrol and fast food.
Cheap skimming devices can be purchased internationally, especially in China, and they can steal small amounts of money from the cards, if they are held less than 8cm away.
E-crime national manager Maarten Kleintjes said there are no reports of this type of theft here yet,but skimming technology will eventually reach this country.
He said there are many ways to foil the theft, including wallets made of carbon plastic or steel mesh.
Skimmers can also be confused by keeping several cards together with credit cards, such as security access cards and snapper cards.
