This is definitely Off Topic
My wife had to go to Holland for a week because of family illness. While there her credit cards were refused, because of an apparently new policy that American credit cards without a "chip" are being refused. Chase Visa Freedom doesn't have them, nor does Amazon Visa. Apparently a Visa Btrish Aorways card may have a chip. Citibank was nice and is sending me new MC cards with a chip.
If you are contemplating using your credit cards on travel in Europe (certainly Holland), make sure you get new ones with a chip. Or be prepared for hassles.
