Seems to be a bit thick for a case at 1cm thickness [1] + it would probably need a screen protector itself.

Yes, for now it is, but it's also stacked so it looks like it's "all screen". Maybe if you could spread components around, it could be thinner.

Somebody else commented this: https://www.gemalto.com/financial/cards/payments/dynamic-cod... I suppose if you can fit it inside of a credit card it would fit a case, and it would be really cool.
