Towards a Digital Money Structure for illiterate Users

In developing countries, although money is becoming digital in the form of mobile money, it is not easily used by millions of illiterate users in their everyday transactions. Digitization of material money thus poses a challenge to many users. Existing mobile money systems and platforms represent money in terms of simple numbers, like 13, 50, 0.78, 23.64, 80 etc. This way of money representation is almost unusable by illiterate users, unless they depend on others’ help. The literature has overlooked the different metadata inscribed on material money (like icons or images, colour , security means, and serial numbers etc). However, these metadata enable illiterate users to identify different currency notes. The material properties of money bills also enable illiterates do simple maths like addition, subtraction, division, and counting. However, current mobile money solutions have not considered money bill’s metadata. Such absence of metadata made money bill identification and transactions difficult for illiterates. The work described in this paper uses the theory of digital objects and theory of non-material technological objects and presents a theoretical presentation for the structure of digital money, to be used in digital ecosystem.
