> In early October, the F.B.I. issued a warning that chip-and-signature cards were still vulnerable to fraud. The original announcement seemed to incorrectly indicate that banks were issuing chip-and-PIN-enabled credit cards, and urged consumers to use the PIN instead of a signature whenever possible. The bureau also warned that the new cards “can be counterfeited using stolen card data obtained from the black market.” Amazing. It's as if they should have just caught up with the rest of the world on Chip and PIN instead of going half the way there.
