What else do you need to know? Feel free to ask, I'm here to help.
Here's a question: what exactly is the nature of the relationship of the Visa Payment Network (or whatever the corporate entity's name is) to this card?
I doubt it is anything other than the relationship between the Visa Network and a bank like Chase issuing a Visa card. Visa aren't going to waste their time cutting special arrangements for such small players.
Assuming I'm correct, I find the 2.5% especially weird given that ANX, as a card issuer, will
receive merchant interchange fees of 1.54% - 2.24% and make money of the BTC/fiat exchange. Smells fishy to me.
