Unresolved journeys or refunds can be re-credited to your Oystercard
instead
of a cheque.

This is not always the case - for refunds organised via helpdesk you have
to be
able to specify a station you will pass through in the next 7 days
otherwise its cheque
only.


That's so they can arrange to take your picture as you collect the refund.
And don't forget, they photograph everyone as they buy the oyster card so
they already have your picture (probably)

You have to specify the station, so that the local computer at that station
is updated, so that it is able to transfer the credit onto your card.
If each gate had to check with a central computer before allowing u thru,
the system would be too slow, hence the distributed network.
