MC and visa regs prohibit the use of the dcc scam unless the potential scamee agrees to be scammed. Period. So having terminals that do not give the potential scamee the choice of whether or not he or she wishes to be scammed would not meet mc/visa specs. I can't believe any such terminals exist; of course remember the clerks in most of these situations don't have a clue; don't know this is a scam and are probably told just push the dcc button and of course few of the scamees know what's going on anyway so they get very few complaints.
