Just received a new VISA card equipped with the 'touch reader' technology. Says we only wave the card over the reader for payment. That seems a bit dangerous to me - if the reader can read the wave...
As mentioned, contact-less credit card transactions are about as safe as using the card's chip insertion method. They both use the same encrypted transaction technology generating a one-time token. Most of the RFID fraud concerns from contact-less credit cards have been debunked as myths.
Personally, I will always use touch credit transaction first, and only use the chip insertion method if not available.
