I never got the dongle though it seems that it would work. Mostly it needs the software, mainly a daemon to detect a NFC thing nearby and then execute a command when it tapped against.
There is enough room in my Mugen/double-Scud/Qi(uses microUSB port) back but running host mode constantly would probably burn massive power and automated USB host mode setup is slow for it to be a thing which scans only every few seconds.
