Normal cards are a solved issue. You can print two braille symbols on each and it is done. Imagine though something like cards against humanity for example, where the text on the card would take ten times the space in braille. In different games images and details could have different meaning and simple ocr would be the wrong solution.

That makes sense!

If the QR codes or whatever are on the faces and only encode information already printed there (suit+rank for standard cards, the title and text for board games) I can't imagine there would be any cheating/unauthorised information problems.

Yep, this is the main idea at the moment. Currently looking for a game that needs the solution and is interesting for my social circle.

Dominion might be a good one.
