So my bday is Monday and i am throwing a burlesque sideshow sort of thing at a local club. Im a sword swallower and this is what I want to do. I want to auction off control of my lush, go around and sell raffle tickets (there will be more than one prize) and let someone control it while Im doing my act. And not die.

Do they have to get an app beforehand or will a QR code suffice?

Im a professional.
