The US Government was sued because a group felt that US paper currency isn't blind/vision-impaired friendly. Citing that all the bills look the same, feel the same, and are the same size. Which poses a problem for those who cannot see when using the paper currency.
What are your views, and possible ideas on how to make the US currency more blind friendly. Personally I never thought about this, but I agree that there needs to be some sort of distinction between the values besides what is printed. I'm leaning towards having the different values have different edges, or texture.
