A system for generating and transmitting summary transaction data includes a computer database from which information is compiled and forwarded to a requesting party automatically, i.e., without the need to interface with a human operator. A party having access to a prepaid transaction account number may access the host computer from a remote location and interactively request transaction information pertaining to the account using virtually any communication modality. The computer is suitably configured to communicate with one or more of the foregoing communication modalities and to automatically compile and transmit the summary data to a requested destination, for example, to a PC. The computer may further be configured to allow the requesting party to select among various formats to configure the form of the summary data. Summary transaction data may be generated and transmitted for virtually any type of prepaid transaction card, including phone cards, travel, credit cards, stored value (e.g., smart cards) cards, and the like.
