You can change your credit card information at any time by by accessing your account details inside Playster's members area. Here's how:
1) In the members area, click the Your Account icon located in the Playster menu on the left.
2) Click the Payment Method tab.
3) Click the green Update Payment Method button.
Please note that upon changing your credit card information, a $1 authorization fee will show up on your new card's statement. This is a requirement for credit card validation. However, this fee is always refunded, normally within 72 hours.
Note: Debit cards having a Visa or Mastercard logo on them are accepted.
