Oyster was meant to be updated to ITSO technology but it doesn't appear
to be happening. I believe its a similar situation at SWT.

I think that the basics for Oyster/ITSO compatibility must be in place,
because all Freedom passes issued in the last few months speak ITSO as
well as Oyster (although I imagine that the Oyster implementation is
quite basic on Freedom cards).
