There is currently a limit on how many different PN master accounts you may associate your credit/debit card to. The maximum amount of PN master accounts that are allowed to have the same credit/debit card number is three. Should you attempt to use your credit/debit card on any additional accounts, you will receive the error message, "The credit card you are attempting to use has already been used for too many accounts. You will need to use a different credit card." This limitation is in place to help alleviate any credit/debit card theft or fraud issues. When your credit/debit card has been used on an account for activation, non-recurring billing, or an actual subscription billing, the master account is counted as one of the three accounts. If you have used the credit/debit card on more than three accounts already, you will not be able to use that card in our system unless the card remains on recurring billing on one of your accounts. Once the credit/debit card is taken off of recurring billing, you will not be able to reuse that card on that account. Removing the credit/debit card on any of your accounts will not release that account as one of the three. Your credit/debit card can always be used on an account as long as it is on one of the three accounts. ------ 젭왈 3줄요약으로  좀 해줘 횽아 .ㅠ
