If you were to venture to I-Drive in Orlando or Times Square with a non-USD card, I'm certain you'd start collecting DCC data points all over the place. It was reported a few years ago in the thread here that even large chains like Red Lobster and Olive Garden had DCC at one point. The reason we don't see it is because we and those around us are predominantly using USD cards, but DCC certainly exists. Many big box electronic and clothing retailers have it, but it's easy enough to decline. Here is my sister-in-law's AUD card at Kate Spade for reference:



This was early 2015 so pre-EMV, but I doubt things have changed. We collected a few data points, but seeing as though her card had exchange fees, we limited the transactions. We currently only have one non-USD card at home, but Mrs. Majuki doesn't like to use it since there's a currency exchange fee and no rewards.
