I have a European chip and pin card. The area around the contacts above the chip has a slight, but noticeable, bulge. I have a newer American chip and pin card.

I have a European chip and pin card. The area around the contacts above the chip has a slight, but noticeable, bulge. I have a newer American chip and pin card. It's thicker but the card is perfectly flat. They also did away with the bump letters and numbers.
