Slightly tangential question but why is credit card security so weak in the first place? I mean all we need is 16 digits of card number, 4 digits of expiry date and 3 digits of CVV. The 23 digits can leak from so many places.
In this day why don't the credit card payment systems require multi-factor authentication for online payments? Why don't payment machines challenge you for PIN for payments?
