Tap is a pocket-sized, lightweight timeclock with a rechargeable battery. When it's time for payroll, just use the included USB cable to plug the clock into the PC running the TimePilot software. The clock-in and clock-out data will be downloaded into the software, the time on the clock will be reset to match the time on the PC and the battery will be recharged. It comes with PC software and enough iButtons for 10 employees. Have more employees? Just add iButtons.
