e-wallet prototypes

Abstract

The design outcomes of this paper are four e-wallet prototypes. E-wallets are intended to replace the existing physical wallet, with its notes, coins, bills, photos, plastic cards, loyalty cards etc. Four different user groups, including Young Teenagers, Young Adults, Mothers and Business Men, have been involved in design and test of the prototypes. Interviews and user tests have provided data for the construction of first a conceptual model, in the form of sketches, and later a functional model, in the form of mock-ups. During the design phases, knowledge was gained on what properties, including design, functional, service, and interaction, the user groups would like the e-wallet to hold. The properties have been to develop four prototypes, one for each user group. © 2011 Springer-Verlag.
