"TfL is starting to issue inspectors with portable card readers which
will be able to read the card???s recent journey history."

Which contradicts what I thought I'd read about contactless card
technology and the ability to store recent transactions on the card

That could be a poor description of a device that reads the card's
number from the card and checks that it has been used to pay for a
fare on that bus.

That makes it sound like the device can read the paper printout too,
so it has something to compare the cards with

I assume that instead of or as well as the paper printout a digital
copy can be be sent to an inspector's portable device.

That sounds like a bigger modification to the bus terminals than just
printing out a slip.
