petrol stations for some reason seem to be where a lot of card cloning takes place.

lots and lots of different methods of obtaining the cards details, through to electronic means to stealing them.

Some wronguns can copy the details held on the magnetic strip and record them onto other devices...mobile phone sim cards, top up card ..well any card with a magnetic strip really.

You can have lebanese loop type devices...old skool

I hard one of one the other day, cant remember if it was at work or not, where you bank card gets stolen and they replace it with another stolen bank car (obviously been maxed out). They then get an extended time with your card as you see a card in your wallet byt dont pay attention to the details on the card.
