But, if you're headed to Europe, beware: not all chip cards are created equal, and your card may be declined in some places, including while trying to make in-flight purchases on certain airlines, as TPG himself experienced on Ryanair.
The issue comes down to how your transaction gets verified. For a long time, Europe has been using a chip-and-pin standard for its credit card transactions. Chip cards have only become common in the U.S, in the last five to 10 years, and even so the system used in the U.S. is different from the one in Europe.
American credit cards work on a chip and signature system. While shoppers in Europe enter a personal identification number during a chip transaction at checkout, American buyers are supposed to sign their receipts to verify that they are the person whose name is on the card.
