How does a clearly visible and cryptographically weak 3-digit code add any security to credit card transactions, unlike common best practices for passwords?
In: 3
It’s adding a step of needing to have physical access to the card. That number isn’t encoded into the card. Would you agree that not having that number would lower the security of the card, even if you think it’s a small amount?
If someone was able to get my credit card number through illicit means, it doesn’t mean they have the 3 digit code unless the card was physically stolen.
