Hi!
Does anyone know anything about NFC (Near Field Communication)? Where can I find more info? Has anyone integrated it with EMY?

Hi Rune,
NFC is a network protocol, EMY is a client side library. There is no such thing as integrating EMY with NFC …
At best, you can connect an EMY app to a NFC reader via UDF / WebSocket.
A NFC reader connected to a ESP8866 could do that for cheap I guess.
But that’s pure Javascript, not really something related to a frontend UI library.
Cheers,
Remi

Interesting!
I use över 200Kb JS code, without counting EMY. I can very well add som Kbs to it in order to make NFC work.
In some industries the information the company owns is what really gives the company it's value. In those cases they guard the information at any cost. I thought it would be a great sales argument for such a company if my APP would be able to data transfer using NFC instead of data transfer via the server.

NFC is an RFID technology (NFC is near field RFID), not a way of communicating arbitrary data between devices.
I guess you should look into encrypting the data you need to communicate.
I don't see that many ways around talking to a server of some kind to communicate between devices from web environment.

If you want to transfer datas between two computers, the only other way i see would be a P2P communication via WebRTC. I never did try it btw.
WebBluetooth might be a way too.
But nothing here helps with NFC btw.
