System, method, and computer readable medium for settling micropayment transactions to a pre-paid instrument

The invention provides a system, method, and computer readable medium 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. In a system of the invention, 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.
