Summary This essay aims to elaborate the technology when it comes to banknote making for visually impaired members of the society. The visually impaired are divided in three subgroups: colour-blind, partially sighted and blind people. Their first needs are useful denomination features rather than security features, as they help them in determining a banknote’s value. This study provides a historical overview of banknote design features for the visually impaired. Furthermore, it looks into the methodology of banknote tests for the colour-blind, showing images of how the colour-blind experience the euro banknotes. Two features are needed for every subgroup of the visually impaired to establish the banknote’s value; one is not reliable. These two features are dedicated firstly to the relevant user group, but will also be used by others, including people with normal vision.
