I have a Client using a digital hand print system for 13 locations and over 900 employees. There is nothing magical about a thumbprint or hand print. Once the timeclock system recognizes the initial print, it creates an analog of the thumb or palm. When the employee clocks in/out, the print is recognized and verifies who the person is clocking in/out just another way to enter the Employee number. Once the day's or pay period data is complete, the timeclock system exports the data to Sage 100 Timecard or Payroll system. Sage 100 doesn't care how the timeclock data is collected. In my case Timeclock Plus has the csv export compatible with Sage 100 Visual Integrator already done for you.
