Unfortunately I can only test this with neard-tools' nfctool, which
reports a tag (from another phone) has been detected but does not allow
me to show its contents (I may have simply not figured out /how/), and
the other phone with the "NFC Tools" app shows nothing when trying to
read from any of the kumano phones (but then I am also unsure how to
"present" a tag via nfctool, and expected it to be implicit when running
as "initiator").

Debug/testing advice appreciated :)
