Close your eyes, take the paper currency from your wallet or purse and tell someone around you what the denominations are. Can't do it? Welcome to the world of the 4.4 million Americans that are blind or visually impaired who have been struggling for years with this problem. Some of you know that I lived and worked in Switzerland. Their currency, the Swiss Franc comes not only in difference colors but the different denomination sizes. Quite easy for a blind or visually impaired person to know exactly what they are holding in their hands. Printing denominations in different colors is certainly a start but not the final solution. Different denomination sizes is the key to change in our society and the US will soon embark upon those changes. The change comes as the result of a decade long legal challenge mounted by the ACB - American Council of the Blind - an organization that represents the blind and visually impaired in the US. In 2008, the US Court of Appeals upheld a lower court ruling that found that the Treasury had discriminated against blind and visually impaired people by printing all denominations of currency in the same size and texture. This was a violation of Section 504 of the US Rehabilitation Act of 1973 which prohibits government programs from discriminating against the disabled. The US Treasury and its Bureau of Engraving and Printing (BEP) have been testing a variety of remedies according a 2009 commissioned report including presenting the options by a blind focus group at the ACB annual convention. It's not over yet but forward progress is being made.
