The development of new applications of electronic commerce (e-commerce) that require the payment of small amounts of money to purchase services or goods opens new challenges in the security and privacy fields. This kind of payments are called micropayments and they have to provide a tradeoff between efficiency and security requirements to pay low-value items. In this paper we present a new efficient and secure micropayment scheme which fulfils the security properties that guarantee no financial risk for merchants and the privacy of the customers. In addition, the proposed system defines a fair exchange between the micropayment and the desired good or service. In this fair exchange, the anonymity and untraceability of the customers are assured. Finally, customers can request a refund whether they are no more interested on the services offered by merchants.
