Is Anything Wrong w/ the Cartio Micropayment System?

ballpeen asks: "Obviously it's not the lack of technology that's been holding up a decent micropayment system for years. But a few months back, I tried out the dummy account demo for the new Cartio set-up, and it seems fine. It's based out of the Netherlands, but fully international. Offers credit card, debit, personal check or cash fills. The s/w downloaded in a couple minutes (400K?), installed no problem on Win98, and seemed to work fine. It's made to handle online and offline purchases in the one-cent to 10 bucks range. Has anyone else checked this out? What's the hold-up?" Of course, this is currently Win32 only (a Mac version looks to be in the works). But the system seems sound enough. Might Cartio be the first to do micropayments right?
