Many transactions on the Internet have a low monetary value: for example, the preparation of a weather report, or the downloading of a chapter of a book or of a font may only cost a fraction of a pound or a dollar. Such transactions would usually attract commission charges from a bank or credit card company much larger than the amount involved; hence it becomes financially infeasible to use conventional payment means to handle them. Microcash is the term used to describe the low-value monies involved. A number of schemes to solve this problem have been proposed. Many involve a purchaser receiving an injection of digital cash via a bank and then spending it in very small amounts, very much like the schemes which operate for pre-paid mobile telephones. See also micromerchant and token.
