RFID chips and credit/debit cards

Many credit and debit cards now have embedded RFID chips to allow contactless transactions in cafes. bars etc. Did you realise that your card's RFID chip could be a way of cloning your card's number and expiry date? Neither did I.

Watch this video to see a demonstration of just how easy it can be to someone with the right technology at his disposal.Sounds like a security loop hole that needs fixing fast.

UPDATE: I am reliably informed that this is not an issue in the UK.
