Given a powerful enough directed RF signal you could certainly power up
and
send signals to an Oyster card from a distance.

Only of you wanted to fry the human holding it, at the same time

Why? It shouldn't need much more power than you'd get from those shop
security gates.

Different technology, and in any case they are only doing a "yes/no",
not trying to read lots of data off the card.
