Most of the rest of the world has moved to chip (EMV) and pin for credit card transactions. The pin is used in place of signature. In the US there are very few chip and pin options, but more and more chip and signature credit cards. Visa and Mastercard have set deadlines for change over to chip and signature cards by the end of 2015, but banks are grumpy about it. I just got a replacement Bank of America credit card with the EMV chip. Capital One hasn't done the upgrade yet.
