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.

How do they get this information in the first place, though? Do they have a QR code reader?

Yes, in that case it's often called Photo-TAN or QR-TAN. See https://en.wikipedia.org/wiki/Transaction_authentication_num...

Previously there were also so called "flicker TAN" approaches: https://de.wikipedia.org/wiki/Transaktionsnummer#chipTAN_com...
