I was very interested in something like this few years back. But, my quick research showed me that

(a) A company called Orbiscom (acquired by MasterCard) had patents in this space [1], and they are the ones behind Bank of America's ShopSafe and a few other such services offered by various banks.

(b) Almost all of those services (except for ShopSafe) are now discontinued. Which indicates that either users don't care about something like this, or that banks don't like offering something like this for some reason. Maybe that explains why nobody knows about MaskMe [2] etc.

I would be curious how Final guys are overcoming those issues.

The industry goes much deeper than that, and there are many vendors that also issue virtual cards via other methods. Checkout Wex & Conferma for a few.

A few big changes are happening on the backend of payments that we also plan on leveraging. See this spec if you want to learn more about them: http://www.emvco.com/specifications.aspx?id=263
