There is encryption and there is also a hand shake that is done.  Its
more like a wireless smart card rather than RFID.  Its bi directional
communication.  Typically, it will send a number, then the credit card
company will send you a different number based on that number and you
will send it a different number based on that number.  These will use
a secrete number on your card that you can't really access. at least
not easily.
