I can attest. It supports both "one shot" cards as well as multi-use (with a time limit, up to one year), both with a limit on how much they can be charged.

That said, I don't think it has an Android app, just a mobile website. The app that shows in Google Play is just a shortcut to the website (built by an unaffiliated developer).

And of course, it doesn't even any of the notification stuff, it's just a gateway to your regular bank account. Nor does it have physical cards.

yes, MBnet is awesome. but sometimes some sites don't accept it (when they test the card doing some transactions first), I wonder if Final will have the same issues.
