Or you can take really drastic steps.
About ten years ago I bought a junked 35mm film camera back that had a memo holder, stripped it off and glued it to a Nikon F back.
Now I just tear off the end tab from the cardboard film box, or write the information on a piece of paper, and slip it into the memo holder.
For my Nikon rangefinders, I got plastic memo holders (which might still be available as an accessory in large camera stores, on ebay or at flea markets) and sewed them to one end of the end of the camera straps.
Works for me.
p.s. after a bit of searching:
If they can't be sourced as an available accessory, there are tons of "As Is" film bodies available from KEH for as little as $3.00 each. The trick is to first do a bit of research to be certain that anything you wish to purchase did in fact have a memo holder on its film back, and that the particular camera has not been stripped of its back.
