The Arduino's what? Or do you mean Arduinos?
Sorry about that, I meant Arduinos, edited my post.
I think you wil struggle to get a NFR system in each finger tip and you will have to make one a transmitter and the other a receiver.
It just has to be one reader on the palm of the hand, that'll do.
What sort of thing do you want to sense?
The touching of the two individual gloves. I also want to be able to differentiate a highfive from a handshake by looking at how long the sensors transmit data. However I don't think that works with NFC.
