Isn't paper currency very friendly to blind people?! they can feel it with their hands , because paper currency is also designed for the blind .
very friendly with the blind, they have advantages that normal people have not given by God, why in the end they have no difficulty distinguishing fiat money because they diligently study by relying on hands. but it is not impossible that many android applications will be made by many people to help them.
I agree but I don't think not all country made it friendly for blind people. But of course cryptocurrency is much way worst for elderly people and person with disability, without gadget and internet it's impossible to transfer Bitcoin and other cryptocurrency but maybe if there's a way to make transaction offline and maybe if there's an affordable device like affordable wallet that can make offline or online transaction that would be much better.
it may be true that there are many countries that apply fiat money to provide an opportunity for blind people to be able to distinguish fiat money. even if there isn't, I have to admit they have that advantage in their hands which is given to them which normal people can't necessarily do.
but indeed for crypto it will certainly experience difficulties, because there are many kinds of transactions made, normal people sometimes don't understand, especially those who have limitations with themselves, obviously will experience difficulties. it seems that they will not think about it because crypto itself still has many shortcomings that always make changes in every transaction.
