The machine has been in opperation a few weeks now and has had no real issues other than a minor code bug that was fixed quickly. It has processed a whole lot of membership payments and donations, with only one bill jam. Unfortunately, since the administrator on site did not have a key yet, they were unable to resolve the issue immediately. But, the member posted their problem on our google group and we were able to work out a solution. That is something that I think ANY cash handling machine has; when a bill or coin jams, there is not much the user can do.
