Hi Lifehacker, a lot of people are trying sell RFID blockers to protect your card against getting skimmed via paywave while you are out and about. I was wondering if this was a thing that can actually happen or if they are just scaremongering to sell a product? Regards, Leon.
As more and more cards are wirelessly enabled for PayPass or PayWave or other ‘tap and go’ payment technologies, people are becoming more paranoid about what that entails. Could people just carry around an EFTPOS machine set to tap $99 straight out of your pocket? Can they sit on street corners and steal your credit card details without you noticing?
While the police have linked tap and go cards with an increase in related crimes, most of them seem to be a matter of the thieves actually stealing the card and going to town underneath the $100 limit. But does that mean that the aforementioned situation doesn’t happen?
There have been plenty of situations where security experts have demonstrated how such identity theft using RFID would happen, but few documented cases where this technique has been confirmed as the actual method used to commit a crime. But this doesn’t mean it’s impossible.
The financial institutions who implemented the technology are quick to say that the cards are just as secure as they ever were, of course, but cautious people may in fact find some peace of mind in using an RFID blocker. However this doesn’t mean you have to pay out the nose for an expensive blocking wallet — you can make your own with silver epoxy or even plain old aluminium foil.
Of course, while this may be a concern of some people’s, one of the big problems with RFID scaremongering is that many will focus on that issue instead of the place where they’re far more likely to be hacked — online. Experts say Australians continue to have a cavalier attitude towards online security, despite proven risks — so perhaps before you invest in an RFID blocker, you should invest some time into tightening up your online security.
And remember: if someone does steal your card or somehow puts a dodgy payment through with tap and go, contact your bank as soon as possible and they will reimburse you for any money lost.
