    Abstract: In this paper, a software based prepaid micropayment scheme is developed. Same as all existing prepaid micropayment schemes, profits of the merchants are protected. Furthermore, in this proposed scheme, fairness for the customers is also promised. More precisely, in this new scheme, the merchant after receiving prepaid money can only claim that a customer has already spent a specific amount of money by showing the required cryptographic witness which can only be received from that customer using as a payment. Most importantly, in this new scheme, no public key signature computation is required .Finally, it will be shown that owing to the simplicity and high performance of the scheme, it can also be employed by a small electronic equipment as the general purpose resource access control.
