TimeClockWindow uses a Microsoft Access database for data storage.
We are not sure of the limitations, one of our customers reported that they have 100 computers with 190 employees using the system. If you have a larger network using TimeClockWindow, we'd love to hear about it.
Watch for news of our new Internet based Time Clock system that is under development that will allow your employees to punch in from smart phones, portable computers, tablets and such as long as they have an Internet connection.
