And that has to be tempting for some companies out there, especially those who do a lot of business in tourist areas.
Well, nothing prevents DCC in a swipe-and-sign environment either. Apple Pay and the like could reduce the prevalence of DCC since DCC isn't allowed for contactless payments with no cardholder verification required.
I maintain that DCC isn't that prevalent in the US to begin with, but my spouse isn't letting me use her Taiwan issued Visa debit card to find out. She let me try one purchase at Mitsuwa, but there was no DCC.
