XQD versus CFexpress Type B

A shared form factor does not establish device or firmware support.

Computer-generated illustration, not a photograph. — P123 · ConnectorXQD card interface

How they differ

XQD card interface Read the XQD marking and the exact reader and camera descriptions. Keep model-specific firmware notes attached to that model.
CFexpress Type B card interface Read Type B on the card and the exact supported-media list; record the camera firmware requirement where one is given.
