Is it wifi connected? bluetooth? nfc? How much control do you have over the app running on the device?

app 1 will be wifi connected but app 2 can have 4G, or wifi, depending on the place. they could be on different networks if your asking about that. nfc, not all devices have it, camera they all have thats why i choosed qr code approach. but you could convince me to use nfc if its a better approach.
i’ve 100% controll of both apps…i’m building the 2.
If you’re going to be WiFi connected, you could look into use Autolan. It lets you setup TCP/IP connectivity between devices. There is also a ZeroConf plugin that makes discovering network devices easier. Once you’re connected, you can then do socket level communications to pass a message from the phone to the kiosk after it scans the QR code.
At that point you would be authenticated.

The 2 users can be on the same network, but they also can be on different networks. A call to a remote server will always be needed (middle man). I just need an effective way to the “server” (the interactive table) to “listen” for a remote request and accepted it. what i need is to the app 1 to connect to the remote server and wait for a “join” request, after a positive request from app 2, it will start an 1-1 connection not accepting any more requests till the connecting is closed on app 1.
I still think a combination of the ZeroConf plugin and AUTOLAN may be your solution. ZeroConf can help your customers discover the kiosk and once you’ve not network addresses, your customer app can open a connection to a server running in your kiosk app.

i will give it a try Rob, thanks for the advice.
