The ability to have permanently online barriers, ticket machines etc
within a few years will mean there will be no need for smart cards to
store data locally. NFC, barcodes etc with an online back end are far
more practical (and media agnostic), while contactless credit/debit
cards will win out for local travel.

Are you also anticipating permanently online RPIs? And all of this
(barriers and RPIs) over the entire country.
