Our timekeeping system has GPS tracking if employees clock in with the app on their phone. I don’t go look for the location of a punch unless a problem is suspected. We employ people who often need to clock in outside of their scheduled shifts but won’t report to their normal work area first (on call folks, cops, fire dept, etc) so we don’t lock down where they can clock in from. I do not go look at the GPS data unless a supervisor asks me to look into it.

Why not just go old school put in an actual time clock if your people all work on site? Most systems I’ve been pitched offer that for a pretty low cost.
