Bidders may consider, for example, TfL ticketing technologies (e.g.
Oyster/Contactless) or a Franchisee ticketing technology that
integrates with the TfL ticketing area."

Well, Oyster technology, not actual Oyster cards.

I presume they mean Travelcards loaded onto ITSO which can then be
arranged to be accepted by TfL gates.

Nothing really clever like PAYG interoperability.
