TAPI: Transactions for Accessing Public Infrastructure

This paper describes TAPI, an offline scheme intended for general Internet-based micropayments. TAPI, which extends and combines concepts from the KeyNote Microchecks and OTPCoins architectures, encodes risk management rules in bank-issued users’ credentials which are in turn used to acquire smallvalued payment tokens. The scheme has very low transaction overhead and can be tuned to use different risk strategies for different environments and clients.
