Many countries have all those features and I doubt they licensed them.Or you can have polymer currency notes with different colours, sizes and even bumps on them for vision impaired people to know what value you have. Just need to license the technology from Australia.
But I never understood why the USA $ is so unfriendly to people with disabilities, the $1 is exactly the same size, shape, and color etc etc as the $5, $10, $20 and $100 notes, I think it is the only paper currency I have come across that does this.
