don't people get this? with microcurrency, you don't say to a seller, "bill me for this item". it would rarely work like that at all. instead, it is, "here is my money, please give me the item".

What is the authentication process for the "money" your are "giving" in this scenario?

Varies with the micropayment system. Some proposals are to use Digicash, either online or offline. Others are to use simpler systems, such as S/Key variants or piles of tokens - you'd use some heavyweight payment system like a credit card / ATM / digicash to buy 100 or 1000 microtokens, which you'd use for the actual payments, and which would require less computation to authenticate.

These processes have a non-repudiation service? Cheers! [ psr ]
