Maintaining RH at 50% is mostly to make the paper (cards in the olden

higher RH the paper stiffness suffers and it swells imparing feeding.

Not true at all. A high RH contributes to failures in electronics
as well. Even recent equipment is specified from 40-60% RH, over a
fairly narrow temperature range.

A production laser printer will be wadding up paper long before the
electronics start complaining. If the paper is too wet it will curl
when it goes through the fuser. A big printer shoving that paper out
at 3 pages a second will turn the stacker into something that looks
like a carnation.

That may be true, but it doesn't mean it's only the printers and
card readers that are in controlled environments.
