The simple fact is that your credit card has to send data back to the RFID reader but your card only has the power to transmit 1-4cm. That limit was specifically designed to prevent illegal scanning. And that's assuming perfect conditions where both your card and the scanner are perfectly still for a few seconds, with the scanner perfectly on top of the chip. Not going to happen. Thieves can improve their scanners all they want, but it's the chip that matters and that's designed by your credit card company.
If you're really paranoid about it, the simplest solution is to line the compartment carrying your credit card with a sheet of aluminum foil. For wallets, just place a sheet of foil in the main cash compartment. When you fold your wallet, the card will be shielded. Takes only a few seconds and you've just made your wallet or bag RFID-blocking. If you don't believe me, wrap your credit card with foil then tap on an RFID reader to pay. It won't work.
Here's an excellent Q&A on the topic in the RFID Journal. It's where experts discuss RFID technology
