Netpay micropayment systems

Xiaoling (Sharlene) Dai continued a PhD with me in the early 2000s working on NetPay, a novel, off-line micro-payment system. We developed several prototypes, architectures to realise the system, conducted several evaluations and then applied the approach to peer-to-peer information exchange and other domains. The basic concept is to support off-line validation of e-coins; support both client-sdie and server-side e-wallets; and after-purchase redeeming of e-coins with a broker.
