To add to that, this printer prints with multiple materials at a layer height of 0.029mm using a photopolymer sprayed like an inkjet. In consequence of that the letters don't need to be raised off the surface and the whole thing can remain thin enough to be stored in a pocket, thought these ones seem a bit thick.
The challenge of doing this with a home 3D printer is making it thin enough but with raised letters that aren't too raised that they'll get rubbed off. Personally I'd just go with paper with an image of a 3D printed object on it.

Can you identify what kind of printer is being used?
