RFID Skimming is a form of digital theft, which enables information from RFID-based credit, debit and ID cards to be read and duplicated.
It can be used as a form of credit card and identity theft and works by covertly reading RFID chips from a distance using a device which downloads the card information.
The stolen information can then be written to a new blank card, which operates just like the original card. It makes no difference if the original data is encrypted or not.
If your credit card does not have an EMV chip, but does have RFID, you have a valid concern.Your bank should issue you a card with RFID or one with an EMV chip.
The idea of RFID in a credit cards is a ridiculous idea.The data can be intercepted much easier than stealing the card itself.At least you have the advantage of knowing when your card is stolen.In a walk-by scan you have no way of knowing until you begin to notice transactions that you didn't authorize in your account statements... And you have to be looking for those to find them a lot of times.
