I know how it works BTW, the thing actually works a bit like a credit card scanner, and the fines from gaming go onto your bill for staying at the hotel.
Unfortunately I can't get the dadgummed thing open without breaking it. If I could afford it ATM I'd buy the thing right off the hotel and pay for another one (but I can't).
And let's see, that request for the box it plugs into... there's a wire that goes back into a hole in the TV stand.... it leads to that box...
Oi, not enough light to take the photo, I'll wait until the morning to do it. But to explain it... the box is black, and it looks like it has a cable out on it.
