The OnePulse card was specifically designed so that the payWave and
Oyster elements of the card didn't conflict,

It might just mean that there's no interference when used with an
only-Oyster or only-Paywave reader. Richard says that there's "trouble"
if you have Oyster and Paywave adjacent on different cards.

so my understanding is that they are in at least one sense 'connected'.
(Curious why you think such a thing is almost impossible to believe?)

Sounds like it could break every crypto rule in the book, for both
halves, if it was a data connection.

But I suppose it's possible that the first one to feel itself being
energised could switch the other one off.

then it's like
having an Oyster and a PayWave in the same wallet, which already
causes trouble. My wallet, with Oyster, ITSO and a Spanish one (not
sure what standard that one is) is guaranteed to fail!

Well, what we can be sure of is that no-one at TfL could possibly have
considered this scenario...

I'm sure they've thought of it, but the answer might be "sorry you can't
use them". iirc it was touch[1] and go that the Onepulse project carried
on (ie that any of the cards were replaced when they expired).

[1] Sorry.
