Question: how accurate is the GPS when employees ClockOn in/out

Answer:

It depends on the employees phone. GPS satellites broadcast their signals from space with a certain accuracy, but what you receive on the phone depends on additional factors, including satellite geometry, signal blockage, atmospheric conditions, and phone design features/quality.

For Example, GPS-enabled smartphones are typically accurate to within a 5 meter radius under open sky However, their accuracy worsens inside buildings, bridges, and trees.
