What would be the purpose? Only to be able to spend bitcoin (albeit indirectly) literally anywhere Visa is accepted. Sure, this is an interim measure, but hugely useful as we wait for the world to catch up to us in bitcoin adoption. The significance of this is large. Sorta like a BitPay/Coinbase type conversion solution that we get to drive from the buying end of the sale, rather than waiting for the seller to adopt.
I'd not before been aware of coincashcard. If legit, I'd sign up immediately. Kind of expensive, but that will likely change as competitors enter the market. The site is largely devoid of concrete info though. Has anyone here used their services? Who is behind it?
I'm sure you could buy prepaid debit cards with bitcoins, but what would be the point? It'd be much easier to just pay with a phone or have someone scan your qr code and you put your pin in like you do on a regular chip and pin or something.
You're not getting it yet. With a Visa-branded card funded with bitcoin, you can spend your money literally everywhere that takes Visa. (What's Visa's tag line? Oh yeah. Visa - everywhere you want to be). The seller doesn't need to display a QR code. They already take Visa.
