Hi,

I am trying to read one specific value out of the global variable 'token'. But like you can see, the result is 'undefined'. So I think that the first lane isn't correct, can anyone help?

You are trying to read the global `TOKEN` but that is not a global variable you have defined. If you said `var VALUE = global.get("rfid") || []` you would get something back.  
You then use `VALUE.TOKEN` to access it’s contents.

P.s. why are you using a capital letters for variable names?
