The electronics package is tiny, and the battery itself is by far the biggest component. I think it makes sense to keep it semi-single-use with those factors in mind.
In fact, I’ve considered 3d printing a new shell for it to make it even tinier and definitely water proof.











As a valid work visa holder in multiple countries, they already have my biometrics as they were a part of the visa process. Having the same data in my passport just speeds things up.
