Transaction history of Paywave cards

[Roland Perry]

Paywave cards are now accepted on London buses (in a very basic 
configuration, no daily capping, no use on the tube), as an alternative 
to Oyster.

If a ticket inspector wants to check your Oyster card on the bus to see 
if you have paid, then it contains a recent journey history (10 
transactions I think).

Do Paywave cards have any history stored on them - even as minimal as 
the time/date/amount of the most recent usage?
