Guidance for extra credit.

I have came across a video of 2 guys who created a MiM laundry card hack. Essentially their MiM is another card that goes into the machine and works off the balance of your original card but the machine never gets the credits depaoited from your original laundry card.

Im just looking for guidance on how this can be achieved as i have an extra credit assignment and this would be very cool to present.

Note: i have contacted the washing machine company and they did give me permission and thanked me for letting them know. The caveat is i have to submit all my data and if i make a MiM card to them after i finish my assignment

heres the video
