Abstract

We present new micropayment schemes that are more efficient and user friendly than previous ones.These schemes reduce bank processing costs by several orders of magnitude, while preserving a simple interface for both users and merchants. The schemes utilize a probabilistic deposit protocol that, in some of the schemes, may be entirely hidden from the users.
