Credit cards with an embedded smart chip are called EMV cards (for Europay-MasterCard-Visa). And American banks, realizing that their outdated credit card products are keeping people from doing their shopping when they travel overseas, are beginning to deal with the whole credit card acceptance
Not to be too hard on the American banks for holding off so long on innovation. The reason Europe was an early adopter of this technology was that they believed that credit cards that held their information locked up in a chip protected by a secret PIN number would be far safer than a credit card that was open to the world with information in a magnetic strip. They also believe that credit cards like this would be harder to counterfeit. There's no reason why these beliefs should be mistaken. Except that they are.
American banks have found that EMV credit cards are actually stolen from, a lot more than magnetic strip cards, for some reason. The expense it would be to throw away every credit card reading machine in America and replace it with a new one is understandably a concern too. Until the industry sorts itself out, problems while you travel to Europe, Canada or Asia, are only to be expected. While their card readers certainly are capable of accepting magnetic strip credit cards from the other side of the Atlantic, the clerks who man those desks and operate those machines have never actually seen a magnetic strip credit card and have no idea what to do with them.
Since most clerks will refuse to put in the extra effort it might take to figure out how to use your credit card, carrying a prepaid EMV debit card would have to be the next best thing. It would guarantee credit card acceptance for you.
