iOS Question read temp using NFC

Hi guys,

I'm looking for information about NFC in iPhone7,
I don't have an iPhone7 (..yet)

Is it possible to send a data(or number) to the iphone using NFC?
I know the new iphone can only read NFC..

NFC references: ref1 ref2

I want to do something like that video minute 2:22 or video2 or video3
Thanks for any information
