Locations
Pings around each swipe.
Vehicle identifier, timestamped location, and any fuel or engine fields you already store. Verizon Connect's public fleet products cover GPS tracking and reporting. I use that history. I do not install a competing ELD.
If pings are sparse, more fills stay unverifiable. I will say so. I will not paper over a quiet device with a guessed location.
It is common to see Verizon Connect on the older trucks and Samsara or Geotab on the newer ones. I match each device to its tractor. Pretending the fleet is one brand is how a report quietly drops units.
