When the credit/debit card linked to auto-topup expires, then they send
you an email asking you to update your card details (i.e. enter the new
card details), and advising that if you don't do so within a few days
they'll block (hotlist) your Oyster card. You get much the same email
if they've tried and failed to charge your card, e.g. if you've
cancelled your card after having lost it but not updated them with the
new card details.

I'm not sure if they send a reminder before the expiry of your card -
they should of course (indeed they quite possibly do - it's just that
the 'urgent action required' email sticks in my mind a bit more after I
lost and subsequently cancelled my debit card).

I'd imagine that the Oyster element of the OnePulse card wouldn't be
treated any differently in this regard compared to a normal Oyster card
(as I said earlier, there seems to have been scant integration of the
backend systems).

It'd be a bit ironic to change the credit card linked to the OnePulse's
Oyster, to a different card. But I suppose if the two are only loosely
linked (ie they don't automatically update it for you when they issue a
new card) then it's fair game.

Unless something has changed of late, deactivating auto-topup on an
Oyster card actually requires one to make a (Tube/rail) journey - which
is less than ideal.

Just like you have to, when you enable it.
