Playing FFXI requires the use of a credit card with the 3D security feature (for reference to any new players). This means only specific Visa or Mastercards are accepted. Visa's version of the 3D security is called Verified by Visa, while Mastercards is called Securecode.

For Visa cards you can check to see if your particular Visa is compatible by going to their Verified by Visa site, and clicking "activate now". It will either help you set it up or tell you it's not applicable.

Finding cards compliant with the 3D security can be tricky though so I thought it would be a huge help to have a thread for known cards that will work.

I've used the AccountNow Mastercard (Mastercard NOT Visa version) in the past, and I can say for certain it will work.
