PlayStation Network (PSN) Cards are voucher codes that allow the user to add funds to their PlayStation Wallet without the need for a credit card. PlayStation Network (PSN) Cards can only be used on the PlayStation Network (i.e. not with local or online retailers). The PSN Card, when redeemed, will place the face value of the card into the PlayStation Wallet (click here for details on how to use a PlayStation Network Card). You may use the funds in your Wallet to purchase downloadable games and add-ons for the PlayStation computer entertainment system and the PSP portable entertainment system.
