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 small-valued payment tokens. The scheme has very low transaction overhead and can be tuned to use different risk strategies for different environments and clients.
