You mean that the chipset used in PineTime can straight up do NFC itself (no extra controller required) when connected an antenna to pins 9 and 10?
Hmm.... My idea might be completely bonkers (Dr "Bones" McCoy's voic: I'm a doctor, Jim! No an RF antenna engineer) but would be possible (with the help of either a MUX chip or physical switch) to alternate between driving the screen or the antena?
i.e.: display turns off, use antena, NFC transaction finishes, antenna shuts off, diplay turns back on ?
