My post was based more on *existing* RFID implementations used for physical

I know that non-contact cards such as RFID Credit Cards use encryption so
on... But are still vulnerable to non-authorized transactions.. I'm mean..
there is no green button you push to authorize the transaction.
But I just don't believe that the RFID access-card I use to access client
premeises use any type of encryption or only communicate with specific
readers.
IF* this is the case then an attacker should have no problems powering the
card and making a "copy" of the contents.
so what's your question then? how your card works? or how to make it secure?
