Just an idea. Take it and run with it if you like it.

This forum isn't very busy. But, that's OK as I don't have much interest in the honor box vending myself.

However, if I did, here is something I might try. I might try to rig up a little switch / sensor / something that could chime a happy chime when someone put money in. And, if I was doing it, an LED that lit up a little "Thank You" sign. I can't help just think a little audio / visual "reward" for doing the right thing and paying might encourage most people to do so. And, it tells others that they paid as well, that might be useful in a break room.

Hack a couple up or ask a friend (or friends kid!) to and see what happens. If I get bored and make one, I'll post back...but I have no reason to make one other than for kicks.

Along with the QR code thing of my other post, seems like two things that might help those that are running this type of route.
