It would be interesting to try to have actual registration so that the embossed design can interact with the printed copy rather that just being an arbitrary background decoration.

The way I understand your comment is you could have a scene or objects printed on a card, then line up an embossed design over the print to create depth or imprint specific areas of the print creating various effects. That would be interesting

also a tool that generates the emboss pattern based on the design of the card. so that for example a logo on the card gets embossed.

I think that was not done by embossing but by "3d printing" on the business card directly.

I don’t know what you mean. The technique of stamping the numbers on credit cards was literally called embossing.

Here is a video of a desktop scale embosser used for just that purpose: https://youtu.be/5ZQHSsFnACs?si=DWwgTScwl5HXkwGP

The part where the embossing daisy wheel is shown is at 18:10.

Here are machines used at an industrial scale: https://www.maticagroup.com/technologies/embossers/

They are nevertheless called “embossers”.

The embossed numbers were used to transfer the details quickly and reliably. A roller would apply pressure to press special paper onto upraised letters and numbers. The seller would hand write the amount and the buyer would sign. Two copies were made simultaneously (carbon impregnated paper) and separated and a copy kept by each party.

Its a far cry from paying by bonk and your phone beeping a few seconds later to indicate your bank has already registered the transaction!
