The following section will be added to the PlayOnline Member Agreement under Article 5 "User Responsibilities" and will take effect as of Jul. 29, 2009:
5.2(e) Credit Card Authentication.
For your protection, SEI now requires that all new credit cards used for Fees be registered with either Verified by Visa(R) or MasterCard SecureCode(R). Please go to
www.verifiedbyvisa.com or
www.securecode.com to register your credit cards. If you do not register your cards on one of these sites, or if your credit card issuing bank has not signed up with either service, you will not be able to access the PlayOnline services. In such case, please contact your place of purchase for return, refund, or exchange subject to the return and exchange policy of the retailer. If:
(1) your place of purchase is unwilling to accept returns or exchanges of opened software AND
(2) you are unable or unwilling to register with Verified by Visa or MasterCard SecureCard AND
(3) it has been less than 30 days since you purchased the software, AND
(4) you are located in the United States or Canada, THEN you may contact PlayOnline Information Center at (858) 790-PLAY (7529) and request a full refund of your purchase price for the Licensed Software, not including shipping and handling charges. Please note that any refund is discretionary and will be contingent upon SEI's receipt of the complete Licensed Software package and confirmation that your credit card is not compatible with either system.
The PlayOnline Member Agreement can be found under "Rules & Policies" on the FINAL FANTASY XI official website or from "Rules & Policies" within "Service & Support" on the PlayOnline Viewer. Please read them carefully and make sure you understand them before you play the game.
