So what *is* the action they refer to as "picking up cards going through

probably that if you've got an incomplete journey and you enter at a
station that has been marked "autocomplete" then you get your incomplete
journey autocompleted by assuming you exited at that station to complete
the journey.

It will work fine for the 90% of people who are going to an event and
return via the same station.

Many of the rest will also probably be fine but I suspect there will be
a significant number of people who accidentally discover themselves in a
crowd for an event and deliberately plan to avoid the "autocomplete"
station for the return trip (or who aren't making a return trip at all)
