if
contactless starts to be accepted on national rail for longer journeys someone
could in theory fleece a TOC of a few hundred quid.

Isnt't the max for contactless £40, hence that has to be the limit of
liability.

The trader can voluntarily, at their risk, accept them for a greater
sum.

Not very likely though in a National Rail context.

And that's before we've looked at the complexity of national roll-out of
the equivalent of pink route validators, and checking if the traveller
sat in First or Standard,
