So, who's the issuer of this MasterCard? Whats the BIN?
Also, does MasterCard know that you are putting Bitcoins on the card? Because they wont be happy at all... In fact, they will most certainly knock on your door and tell you not to do that anymore or you will loose your issuing license.
Judging by the thread so far I am expecting somebody to say "Nu-huuh, BitPay are giving us dolla dolla bills, thats not bitcoin and its no problem for MC"... but the truth is that MC will shut you down just because somebody mentioned BTC in the funding process. And believe me when I say, these MC dudes are fuckin mental on the all AML regulation thing thats related to the BTC.
This has actually been covered earlier in this thread. Our cards are issued by Wave Crest, and we are running a fully transparent operation with all involved partners and providers being fully aware of what we do and how we do it. We do actually have efficient AML and KYC policies in place, and so far our card vendor, a certified MasterCard Europe partner, has not had any issues with us at all.
