Previous commenter and I were talking about chip and pin, not just chip (aka EMV).

With EMV, someone can still use your card after they steal it. With chip and pin, that is far more difficult. I don’t know if merchant off the hook even with just chip, I presume the card networks kept some weasel language in order to allow them to blame the merchant.

EMV is the standard for the debit/credit cards with chips. It includes modes with PINs, signatures, and neither, depending on the configuration of the card (i.e. the bank) and the reader (i.e. the shop's bank/intermediary).
