The tickets have an area for the purchasers' info. To save the purchasers the hassle of filling them out manually, we give them a sheet of printed labels. They peel them off and stick them on the part of the tickets that go into the barrel. The randomness is the manual drawing of the tickets from the barrel. Using an electronic method would be scary -- if something went wrong, I don't know what we'd do. And we are licensed by our state to do this. We are a small nonprofit -- only volunteers -- no paid employees.
