    As far as I understand it the pin&chip system involves a challenge/response between the bank and the card. You can’t just “clone” the chip, because the secret data it contains is essentially write-only.

      Sorry, maybe I wasn’t clear.

      I’m assuming the 16 digit card number, start and expiry dates, and CVV are printed on the reverse - whereas it used to only have the CVV on the reverse and the rest of the details on the front.

      What’s stopping someone with a picture of the rear of the card visiting an online retailer and going wild with a picture of just one side of the card these days - aside from multi-factor authentication at the point of authorising the payment?
