I took a trip on a 38 from Piccadilly to Victoria yesterday afternoon.

Unusually, the conductor worked like a Trojan during the trip, checking
fares, calling out stops (with a lot of additional information, too) as
well as warnings. It was a pleasure to see.

My query, though, concerns Oyster.

I paid by Oyster Prepay and at Victoria I left the bus and went straight
into the Underground Station to top up it up. When I did so, I was
astonished to see my journey on the 38 already recorded on my usage.
How does this data get from the conductor's machine to Oyster's "Central
Control" so quickly?

I thought some of this information was stored on the card BICBW.
