It seems astonishing that the testing went so smoothly, especially given
that the cards have only a single chip that can hold both Oyster and ITSO
data (two chips on one card was deemed too expensive). But I guess that
the Freedom Pass is a very simple implementation of Oyster, and I doubt
that the ITSO part has been tested at all, given that the only working
ITSO ticket scheme I know of is on Blackpool Borough Council buses!

Presumably London buses will be able to read bus passes issued outside
London.
