How does this card get connected to retailers? Do they have to sign-up individual retailers? Are retailers accepting Coins or are the coins being exchanged at a live rate?
In my experience doing Point-Of-Sale, these kind of new debit/credit systems are very slow to gain traction. I'd be concerned with their levels of adoption at brick and mortar stores.
well if they get visa approval i guess you would load mco onto your card and its converted to fiat at time of transaction therefore be able to spend in any store that accepts visa which is 99%
