&gt; 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.”<p>Amazing. It&#x27;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.
