I'm in a school senario running BM 3.8. THe school has decided that it
wants the students to be charged and be able to view how much they have in
their tank. If they exceed an amount they can use an ID card which they
can recharge their account.

I know of Ingot, but the overheads are on the IT dept, becuase if they
exceed the amount we would need to top it up....not good!

Is there anything out there....if not the BM box is on dangerous ground of
being shown the door....not good either :-(
