So, I posted a image just as a joke of an interesting way to make money if you are a bum. The main reason is people are usually to lazy to open their window or just don't want to hand cash to stranger. People would be willing to help if they can simply just scan you as driving by.
Well, I looked at my wallet lately and people are actually sending me money to my wallet. Not much money but a few dollars a day adds up.
Anyway, just trying to make you laugh.
