I visited the UK recently, and I was quite impressed by the accessibility of their banknotes compared to the US ones:

* braille on the notes

* different colors for different denominations

* different sizing for different denominations

The UK notes are far more accessible to the blind and the illiterate, and it becomes basically impossible to accidentally include a £100 note in a stack of £5s.

They also have holographic printing like the US notes, but theirs are full images embedded in transparent windows.

I know that it would be basically impossible for us to do likewise (our currency is designed to be backwards compatible, and the vending industry would probably throw a fit if you changed the size of the bill on them), but one can wish.

Keep in mind the vending industry works just fine in countries with variable sized and coloured notes, like UK, EU, AU, NZ, etc.

Oh, absolutely! I just feel like it would be a nightmare to refit new bill readers into all the existing US vending machines.
