I saw this in FedEx office a couple days ago.
It made me think about my past where I was at college. We had to do a lot of printing, and sometimes it ends up with a long queue. Software that allows you to connect to a server, and then pick up the stuff that you need to print, might do quite good things. It’ll allow everyone to send the printing from home, and pick up when they arrive at college.
Of course, the payment will be done on the internet, no more coins being returned or rounded up payment.
