A financial institution, such as a bank, issues numerous uniquely coded travelers checks to various individual entities in exchange for value received. The holder of each travelers check in entitled to receive a certain average rate of income from the dollar-value represented by that check; which average rate of income would generally be proportional to prevailing interest rate as well as to the dollar-value represented by the check. To avoid the relatively high transaction costs associated with periodic payments of a relatively modest income to the holder of each of numerous individual checks, a statistical method is used. By way of this statistical method, a relatively few of the numerous uniquely coded travelers checks are randomly chosen at the end of each of a continuous sequence of time periods, and all the income attributable to all the issued travelers checks for the associated time period is then paid to the holders of the relatively few travelers checks chosen for that time period.
