TfL explained that it could not be aware of any over-charging until
the issue was reported by a passenger.

Apart, of course, from looking for cards where there were two top-up
[bank charges] on the same day.

Yes - some passengers will do that, but that doesn't actually matter.
What you are looking for is top-ups where there were two debits but
only one amount of credit added.

Not holding an Oyster card, I wouldn't know, but in many cases the
financial part of e-transactions is handled separately for security
reasons. If that is the case here, then how would TfL know in detail
about the debits?

If by 'e-transactions' you are talking about an e-commerce (i.e.
online purchase) situation, then that wouldn't apply here as this
concerns people topping up their Oyster cards in person at self-
service ticket machines at LU stations.

No, I was trying to use a short form for transactions involving
electronic fund transfer. I've never been in doubt as to the nature of
the transaction - it just seems from the description as if the systems
in use are generating spurious transactions. My comment was predicated
on the idea that TfL may not have details which would identify whose
five pounds a particular five pounds is, if some other agency handles
the financial part of the transaction.

OK, thanks for the clarification.
