Ah yeah. I understand. The reason tag info shows pages as unreadable versus no pages is that nxp has a version command in tag info so it asks the tag what it is and the ntag family has a get_version command, so taginfo knows exactly what chip it’s talking to and what memory pages it has. I don’t think NFC tools does the same, it probably just tries to read pages until it can’t read any pages anymore and stops.
