Wasn't the original plan for Oysters a card that you could just wave in
the air somewhere in the general vicinity of a reader - in order to
speed up passage through the gates - instead of "Make sure you place
your card flat on the reader and don't slide it around" ?

It was. A group of staff tested the first staff passes by walking past the
gates and every single one opened from about 5 foot away!
