Making up a bunch of lower value pre paid cards

Two of my machines are only cashless,customer running them has ask for 500 cards with $8.00 on each one, being nice and only charging a dollar activation fee so I'll have to do these myself. Those without a valid ID sorry I couldn't find a way around it. These are scheduled to be moved around to a few different locations throughout the summer. Both failed the city inspection but I was granted waivers from the State... as the city credit card cannot be used for alcohol purchases
