Carlos Ithe problem with most products that are adapted to the visually impaired is that they aren’t adapted to all kids of visual challenges and most of the time aren’t well though through.
Adapting bank cards by embossing a few dots will be expensive and will be limited to only a few options. For instance when you offer to emboss one dot for orientation, it will still not tell you which card you hold.
There are ways to achieve both and they are cheaper and more customisable than anything bunq can offer. For instance braille keyboard stickers. They will not only tell you the orientation of the card, but will tell you which card it is. They are cheap and useable on many more items than just bank cards. I have seen visually impaired people use these.
Being visually impaired as well, I often choose to buy products which I customise to my own needs instead of buying adapted product for visually impaired people. Often enough the design doesn’t meet my needs and isn’t very well thought through. Product designers don’t see (pun intended) what we can’t see.
So I would advise against enhancements for visually impaired on bank cards as there are better and cheaper options out there.
If bunq would consider to adapt anything for the visually impaired, let them bring back the dark mode in the app or let one customise some colours in the app. The grey numbers on a white background are really hard to read.
