How easy would it be to just cut out the top of the bag with the QR code and stick it there? Then the machine would squeeze anything inside it within the limited shelf life of that bag. Jokingly I can even see 'the mafia' using it to crush someone's hand in the device. Though that makes me wonder if the machine does provide enough force to do that, and what kind of damage it could do... Anyone can know or figure it out?
