The new chip-cards only prevent the bad guys from using strip-readers to steal your card data. The new cards have no strips, so there’s no way for the bad guys to read the strip.
I have no idea how the bad guys were able to use your card data to make the 2K Euros charge on your card.
Someone suggested that the thieves have scanning devices that capture the vital information, even if still in your wallet. Sounds pretty sophisticated, but criminals always find a way.
