If visitors could just swipe a regular credit card it would save them a
lot of trouble, and still be cheaper than paying a large number of single
fares at inflated cash rates. Such customers might be willing to forgive
the other limitations, e.g. no capping or loading of railcards.

If you read the whole thread, capping is presumed workable, as charging will
only be done on an 'end of the day' basis.

OTOH railcards don't seem to have been discussed at length yet...
