I was at the ATM today when I noticed braille all over the keypad. It got me thinking, ok a blind person could use this machine but how would they know they got the right amount of money in return? As far as I can tell all the bills are the same size with no distinctive tangible differences like in some other countries currencies.

I can imagine this would lead to a great deal of problems for blind people. For those that are able to get around on their own I’m sure there are instances where they have to buy things and thus rely on the other individuals honesty to not take advantage of them.
