Today, all stores in the US should accept chip-and-PIN cards. Yeah, right. | Ars Technica: "On top of this, the US credit card industry isn't fully upgrading to the most secure version of EMV. Although new credit cards will have a chip that generates a new code every time the card is used at a terminal, guarding those cards from fraudsters who collect credit card numbers wholesale and reuse them on counterfeit credit cards, card users are also encouraged to set up a PIN and input that number after every transaction.
