I don't think card readers can display payment information, can they?
And I have no idea why, but no bank offers photoTAN devices in my country. They seem like an interesting concept, even though I imagine the underlying hardware isn't far from that of a phone, in the end.
The card readers have an LCD display that shows the information.
