a user should be able to keep to the "always touch in and out"
requirement -- regular, tourist or whatever. It isn't difficult!

There are still bear-traps for the unwary. For example getting off a
train at a London terminus having travelled that far on a paper ticket,
clutching an Oyster for onward tube travel, and using it to "always
touch out" at the barrier line, results in an unresolved journey.

Then I'll add another item to my "requirements", something I thought
of today and David Cantrell mentioned: make sure that NR stations can
do basic Oyster operations. There is, I think, only one system that
can, predictably the one made by Cubic. In its last days, APTIS could
do Oyster with the right extra hardware, but most of its replacements
couldn't. Fixing an unresolved journey and undoing a journey that was
started in error are the least NR should be able to do. Alternatively
give us a smartphone app to do it! (Some places sell tickets
"through" a smartphone app to a card -- I think RMV in Germany can do
this.)
