I think they would have to get very close, IIRC they would have to get their reader within at least 4 cms of your card. Its possible but its not as simple as walking a round a shopping centre for few hours and walking out with the details of everyone you walk past.
Hmm, tube trains in London?
It depends on the reader and whether you doctor it to exceed the official power limits (I've got one which can, as I did some RFID stuff for work... it's big enough to be suspicious - about the size of a small radio - but I could put it in a bag and wire it to an antenna in a glove or something). If you're worried about this, put foil around the outside of your wallet and it'll prevent most attempts - in my experience, most card readers get unhappy if you keep your card next to your bike and house keys.
i should add that the details they get from this wouldn't let them copy your card; I also dont think they would be able to charge it without a genuine reader.
Not that I know of, but I think it's very likely that scammers have better kit than what's been sitting on a software developer's shelf for a few years and this isn't the sort of stuff that anyone's going to shout too loudly about because it'll scare shoppers and the precautions are pretty simple stuff like checking transactions that we should do anyway.
Oh I agree but we are also sometimes in danger of worrying people too much so they wont even use new technologies because they are paranoid. Instead of checking their bills they will try and avoid any problems altogether by not using the techology at all.
Keep a second card behind it, neither will be readable. Both cards seen as one.
The scanner could simply be relaying the transaction conversation over some other connection (possibly even mobile data) to another person buying shoot with a phone app in a wallet. The shop can't see the card, so can't see they don't physically have it.
They can be read. Even my old kit can see up to 16 cards at once because it's the sort of thing you may want to do for bulk-issuing of cards. I suspect most till software just aborts if it can see multiple cards because it can't tell which you want to use. Scammers won't care as long as they can use something.
She could have said No to getting cash though.I went into the bank yesterday,to order a new card and draw some money out. The woman behind the counter started coughing a bit,then it broke out into a full scale coughing gagging,choking attack! Everything alright? i asked. She jumped up and dived for the water dispenser,saying the air conditioning was choking her. Honestly,she coughed all over my utility bill, passport and community charge letters. Those in the queue were looking at me like it was my fault. I don't think i'll be going in there again in a hurry.
She blamed the cashier next to her for putting the thing on. It wasn't even warm yesterday. Only about 60F.
