Awesome system! Just a quick couple of questions! What happens if a drink is $2.50? what happens to the $0.50? Also, how would people top up the card? Keep up the good work!

I've repriced most of the drinks to be even dollars.. $1, $2, etc. But remember that the pop machine simply sees my gizmo as a bill acceptor. So if you put in $2 and then buy a drink that is $1.50, it will actually give you 50 cents of change from the coin changer.

This obviously isn't ideal since it is supposed to be a coin-free system, which is why I repriced the drinks.

People top up the card by coming to me and giving me money, which I then credit onto their account. Maybe one day I will get a bill acceptor or something
