InstiCheck is a check e-mailing and check printing software, sufficiently powerful for even the more complex check printing task. With InstiCheck you can choose from a number of different check formats like 8.5 X 11 check on top, 8.5 X 11 check on bottom, or 8.5 X 11 3up check. You can also have a custom check format written for your specific needs. Also with InstiCheck, you can feel more at ease when e-mailing someone a check because of the new feature called Key Authentication. With Key Authentication you can help ensure that the person receiving the check can only print that check out one time. InstiCheck 3.0.3 is a total overhaul from 2.0. It includes interface redesign and more functionality.
