Keyed unit
What the card recorded.
Unit numbers
Drivers key a unit at the pump. Sometimes they key their own number out of habit, or last week's truck. The gallons are in a fleet tank. They are on the wrong line.
F. Adeyemi keyed unit 6120 and drove 6210. The gallons were in a fleet tank. They were on the wrong unit. That line goes to dispatch: ask drivers to enter their own unit at the pump. It does not go to a theft file.
If you treat that as theft, you will accuse a driver who fueled a company truck, and you will miss the fills that never hit a tank at all.
On the Southeast fleet of 200 or more, the useful part of week one was the split. Theft and card misuse were more than $2,000. Mixups were a habit to fix, not a crime to allege. Later flags still needed receipts and video before anyone added dollars.
I will tell you the habit in plain words. If the same drivers repeat it, the Monday note says that too.
What I look for
What the card recorded.
What GPS and the TMS say was actually out.
Enter the unit you are in. Not a lecture. A habit.
Short answers
That is your call. My job is to show that the fuel is in a fleet tank and name the habit.
Some cards can. I will not change the card setup. I will show whether the current setup is lying to you.
Next step
15 minutes. If your team is chasing typos as theft, the audit pays for itself in time alone.
