If you put a piece of technology into the world you should spend more time on what consequences that has for the living in the future, not the dead.

As someone who has worked on payments infrastructure before, it's probably nice if your first thought is what great things an aunt can buy for her niece, but you're better off asking what bad actors can do with your software, or you're in for a bad surprise.
