Hey people, we are seeing a big influx of people buying clips using the prepaid/gift cards they got for the holidays. We are also seeing a lot of the transactions fail. Be aware that ALL cards must be registered to a physical street address (including a ZIP/Postal code) before they can be used online or at an un-manned kiosk or fuel pump. This is typically done at the website of the card issuer, and the URL is on the back of the card. Alternately, there's usually a telephone number you can use instead.
Depending on the processing gateway being used, an unregistered card could throw any number of different errors, most of which won't have anything to do with the card being unregistered. Avoid the confusion and do the registration first before using the card for anything.
Big improvement over the last few days, but still a few stragglers. Be sure that your card is even VALID for use in "card-not-present" transactions. A few brands can only be used at brick & mortar retailers. If you are in a country besides the US, make sure the card can be used internationally.
Also, the card MUST be branded as Visa, Mastercard, Discover, etc and the retailer must be able to process that brand. (The Mothership accepts all 3)
Lastly, the card cannot be retailer-specific, i.e. don't try buying fetish porn with an Arby's or Home Depot gift card
