well, i was searching official k2's forums and found this topic:
well, i've been searching PUS and the site for it and couldnt find.Over the weekend a new credit card verification process was put into place on the Power Up Store. This process, which is already live on GamersFirst, creates some new rules for using your credit card in the Power Up Store. This process will need to be followed by anyone wishing to make a credit card purchase, however this is just a one-time verification.
How does this process work?
After you make a purchase using a credit card, a small refund will be made to your credit card. You can view this refund on your credit card statement (online or your monthly paper statement). Once you confirm the refund amount, you can go here and complete validation of your credit card.
What is an AUTH CODE?
The AUTH CODE is the two-digit number found on your credit card statement as a small refund. You’ll need to enter the AUTH CODE here to complete the credit card verification process. You will only have one chance to enter the code correctly so make sure it is correct.
What if I entered in the wrong AUTH CODE?
If you put in the wrong AUTH CODE, you will receive an email saying your credit card validation has failed. You can contact customer support to correct this and you may be asked for additional information to confirm your account.
Can I use credit cards outside the United States?
At this time we are only accepting credit cards from the United States and Canada. If you are outside these regions you'll need to go through your local payment providers such as; Click&Buy, PayPal or ESN codes.
If you have any additional questions on how this process works, please visit the post here for further discussion.[/b]
