I don't know how JPMorgan Chase knew that I would spend $200 on Botox in Argentina, but it did. It's great that banks and credit-card companies are getting better at discerning which payments are fraudulent and which are legit. Credit-card fraud protection is still far from perfect, but there's no denying that the technology is improving. So I reached out to some credit-card companies and academics to learn more. But it's cool that companies really are making fraud detection better, especially in a world where fraudsters themselves are constantly getting better.
