I was trying to look into this as well. Apparently the chips cannot be read from in the same way unless you authorize it. I don't know how that authorization process works, but I'm guessing it's possible. I'll be looking out for Coin in the future when they introduce EMV support.
- PeterisP 13y agoYou shouldn't be able to read EMV chips with any authorisation - it's supposed to be safe from bank employees who make the actual cards, so they can't clone your card before giving it to you. In the EMV process the private key should be unique to the card (if you make a replacement card with the same number, it's a different key); the private key shouldn't exist anywhere outside the chip after the card is made; and there aren't supposed to be any ways to read the key. Well, cutting the chip and scanning with a electron microscope works, but it's impractical. I'm not saying that there aren't any bugs in the implementation, but I'm quite sure that there are no known bugs that allow simply to get the key; even full control of the HSM which holds the bank's private key should allow you only to make/sign new fake cards, but not recreate an existing card.
