Braille does not help everyone. Most people with vision issues are not legally lind and do not know braille.

Anyone able to feel the dots could learn to distinguish bills this way without learning braille beyond that, regardless of their vision.

Anyone who didn't find the feature useful could ignore it.

In canada it's "one cluster of dots = $5, two clusters = $10, three = $20" and so on. You just feel the number of dot clusters & count, no braille involved.

You need a week of low-key exposure to learn how each bill is marked.

It's wild to see you downvoted. Only about 10% of blind people know braille. There are many more people who have visual impairments but are not blind. Braille is not a universal solution (though I would rather have it than not have it).

But you don't need to know braille to learn how the most common bills are marked.

Just like you don't need to know Japanese to count the exact amount of yen bills.

Chiming in to complain that a good, working solution to a problem just doesn't happen to solve ALL PROBLEMS is just banality or perhaps pedantry. Unless it was also proposing an alternative that might do better...

Braille on money also doesn't help dyslexic quadrplegics with dysesthesia... Checkmate.

I think that's an extremely ungenerous read here. The thread is about how different size bills and different color bills solve a lot of problems with people who have low vision. Adding braille solves the same problem, but for a subset of people that different sized/color bills solves.

If you have a good, working solution that's widely used worldwide, and someone suggests a worse solution that works for fewer people, it's more than fair to point out that "your solution is worse, less common, and works for fewer people".

Your last sentence is a low effort strawman, I'm not sure why you felt it necessary to include.

Hackernews is filled with you healthy 20 year olds who do not understand that many will by the age of 30 have reduced vision.

Society is not supposed to be engineered for young single healthy 20 year old males.
