Abstract:

Micropayments are back, at least in theory, thanks to P2P. Micropayments are an idea with a long history and a disputed definition - as the W3C micropayment working group puts it, '... there is no clear definition of a 'Web micropayment' that encompasses all systems,' but in its broadest definition, the word micropayment refers to 'low-value electronic financial transactions.'
