How does having the CVV number prove the card is in my possession? I have memorized the CVV in addition to the 16 digits of the cards I commonly use and routinely enter them into online ordering without retrieving the card. What prevents a fraudster from writing the CVV down along with the other card data?
Nothing, but lots of fraud scenarios don't involve a bad actor taking physical posession of your card: magstripe skimmers and charge-slip carbons being only 2 off-hand examples. Clearly, the percentage of fraud it blocks is more than the amount it costs. Cheers, -- jra -- Jay R.
