Employees simply wave their proximity badge (15 included) in front of the PCEXPRESS wall mount time clock to punch in or out, eliminating contact and reducing the spread of germs. A paid subscription to Lathem's PayClock Online web-based time clock software is required and sold separately. Punch times are transmitted securely by Wi-Fi or Ethernet to the PayClock Online cloud-based time clock software for calculating worked hours including overtime, editing, reporting, and exporting to your existing payroll software including ADP, Paychex, QuickBooks and more.
