The March Towards Micropayments

MattW writes "It's been well over a year since Ron Rivest's company Peppercoin was introduced on Slashdot. Now, the AP is reporting that Peppercoin 2.0 is here. Peppercoin's website indicates that version 2.0 pays merchants exactly what they charged, instead of with cryptographically signed tokens which may or may not sum out to exactly the expected charges. This looks like the technology that will enable credit card acceptance in vending machines and video games, but may not solve the need for truly "micro" payments, like paying $.005 for a page view."
