The TFL employees can definitely see at least some history from your
cards. I switched a pay-as-you god card to a season ticket one time
and the guy behind the counter could see all the 'unresolved' journeys
where I'd touched-in, but not touched-out. Dunno if they have details
of all other journeys too, or if they only persist data on unresolved
journeys...
