The invention provides a method, business method, and system for conducting micropayment transactions between consumers and merchants. A merchant offers micropayment transactions to a consumer. The micropayment transaction is authorized, and the micropayment transaction is executed between the merchant and the consumer. A value parameter associated with a prepaid instrument, such as a prepaid calling card, is decremented by an amount corresponding to the value provided by the merchant. A payment is transferred to the merchant to settle the micropayment transaction. The invention also provides a system for conducting micropayment transactions between consumers and merchants. At least one prepaid calling card is issued to a consumer in exchange for a payment from the consumer. A merchant site conducts micropayment transactions and accepts the prepaid calling card as payment. A clearinghouse receives data associated with the prepaid calling card from the merchant site and processes the data to settle the micropayment transaction. The invention also provides a business method for conducting micropayment transactions between consumers and merchants. The invention further provides systems and methods for effecting remote commerce which are particularly adapted for the intelligent selection and proffer of products, services, or information to a user or customer during micropayment transactions.
