There is a discussion about NFC Tag Type 4 being implemented some time in the future (without specific ETA) where you can chime in to keep the topic collected in one thread.
I’ll also move this thread into the respective/dedicated category (don’t mind the “confusing” cloud part in the category description - we hope that will be changed some time 
)
However, one thing is fix: Gen3 (without external NFC reader hardware) can only ever act as NFC Tag and not as NFC central/host as it hasn’t got the hardware to drive the tag’s power coil.
