Cybercash [PDF ebook] 
The Coming Era of Electronic Money

Cybercash refers to the creation and circulation of online money. The author applies economic analysis to this new form of electronic money to understand how it will enable the internet to re-establish itself as the dynamic centre of the new economy and how this new money form will become the dominant payment mechanism rivalling cash, paper cheques or credit cards. This will be the first book to look at the coming era of electronic money within the broader context of the economy.
