Absolutely spot on, thank you - always handy to know.
I'm wondering what it does to mitigate the "card not present" fraud though, for online purchases or remote purchases?
In my case, I have to verify online purchases on my bank's app. Which makes online banking impossible without an android or apple phone.
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?
Oh! In that case: absolutely nothing. Credit cards are terrifyingly insecure. Whether or not the info is on two sides or one. Any webshop you use your credit card at can just arbitrarily charge it from then on if they feel like it.
The CVV should really be 2FA from your card issuer.
Most card allow you to set that transactions have to be approved either by app or by SMS.
There’s additional tools for e-commerce transactions like 3DSecure (step up authentication like an OTP) and passive identity verification tools.
I just replied this to the parent comment.
