Previously on the Sony PSN breach, Senior Director of Corporate Communications Patrick Seybold had assured users that Sony did not ask for the 3 digit CCV credit card codes; however, yesterday he apologized for the confusion as the codes are actually asked for when making a purchase with a credit card.
Nevertheless, Seybold assures users that none of that data is stored by Sony and are sent directly to their payment processors for verification.
"As our friends at Destructoid pointed out, I was incorrect on the last point of the credit card question above. I want to make an important distinction: While we do ask for CCV codes, we do not store them in our database. It is transmitted to our payment processors for verification purposes only. Deep apologies for the confusion."
