Imagine trying to pay for something in cash with your eyes closed. Depending on where you are from, this task might be fairly straightforward. Or it could be downright impossible. In some countries, like China, Canada, and Kazakhstan, paper money is designed with consideration to people with visual impairments. They include details, such as varied colors, differently sized bills, and tactile features (like raised numbers), which can make it much easier to tell different denominations apart.
While Australian banknotes are different colors and sizes with values displayed in large font, for teenager Connor Macleod, who is blind, they were still a challenge to use. So much so that he attempted to forgo using paper money altogether. Realizing that wasn't feasible, Macleod decided Australia could do even better. Thanks to his efforts - and the over 57,000 signatories of his petition - the Australian government announced plans to add tactile features to their next generation of bills.
Who knows, maybe Macleod's actions will inspire change in the United States too, which remains the only major world currency with bills that are all the same size.
