It appears that Playstation Network and Qriocity users can breathe more easily when it comes to their credit card information.

Sony has stated that a vital piece of information related to purchases, the card security code, was NOT stored or archived by their system.

This code, which is usually three or four digits long, is used to confirm purchases online and by phone. It is printed on the back on Visa and Mastercard credit cards, next to the signature strip, and in the front of many American Express cards, just above the credit card number.

This card verification code expires with the credit card and another code is issued whenever new cards are sent out. So if the credit card you used on the above mentioned networks was about to expire, you should have no problem.

Furthermore, with the introduction of chip cards and services like Visa‘s Verified by Visa and Mastercard‘s Securecode services, information gathered from the security breach would not likely be useable. But I would definately advise vigilance in regards to purchases, just in case.

Canada’s major credit card companies had adopted Zero Liability programs years back for unauthorized purchases so i’m guessing the issue wont cause many problems, though it should be noted that Sony will NOT be asking people to provide personal or credit card information via email or by phone.

BTW, Sony has stated that some of the services will be reactivated this week and some of their users will be eligible for a free month of Playstation Plus. Details can be found on their official blog.
