I have no idea maybe the vendor has set something up allowing you to use it anonymously, up until this point I was under the impression that you obtained the card through a legitimate channel, as it is a legitimate card. Lots of vendors get reloadable debit cards activated with stolen identities and shipped to boxes registered with forged identification matching the stolen identity they used to activate the card. Then customers can send them money by buying reload packs for the vendors card with cash, which the vendor then cashes out at an ATM. This isn't an ideal money transfer scheme, but it is actually quite popular. Perhaps the vendor you obtained the card from already committed identity theft and mail fraud in order to get an activated reloadable debit card, and they are in the business of selling these cards to vendors. I highly suggest that you ask whoever you bought the card from, considering they are most likely to know how to help you. As far as the underground card providers that I am aware of, I don't feel comfortable sharing those here as I don't feel like getting them shut down any faster than they are already likely to be.
