Off the top of the Overdrive Radio podcast this week is the voice of fuel-payments provider Wex's Vice President of Global Anti-Financial Crimes William Fitzgerald, laying out a 1 in 12,000 transaction rate for detection of fraud over the company's entire fuel-payments network. That is, 1 in every 12,000 purchases are flagged as suspiscious, potentially fraudulent, and blocked in automated fashion among its millions upon millions of fuel transactions facilitated annually.

Translate that incidence to the roughly 350,000 fuel transactions National Association of Small Trucking Companies President David Owen knows move through the association’s own Quality Plus fuel network any given month, and that’s right at 30 transactions being held up by the system. William Fitzgerald was speaking at NASTC's annual conference to outline the evolving landscape of fuel fraud/theft for attendees and showcase tools within Wex's (and some other card providers') networks that are increasingly successful in helping carriers of all shapes and sizes eliminate fraud's impact. Along the way, too, the company's been able to reduce the rate of so-called "false positives," legimate fuel purchases held up by the card provider's systems. Fitzgerald's well aware such hold-ups can be particularly annoying, and unproductive. Illustrating the huge financial impact of stolen fuel, though, he asked this hypothetical question to a room of NASTC conference attendees:

"What would be an acceptable false-positive rate in your minds?" he asked. "How many good transactions would you be OK with me stopping to prevent a bad one?"

The goal is zero false positves, of course, as Wex and other card providers calibrate a variety of techs operating in the network's background to get there, in addition to more human-focused efforts aimed at education to prevent account takeovers and the like that can bring the biggest hits to a fuel buyer’s bottom line. Results from ongoing efforts at Wex in particular have been good in recent months, he said. "We've got overall, over the last 10 months, a 25% reduction in losses, a 32% reduction in false positives," and a big increase in detection, too, he said.

Those results he attributed largely to technical innovations in company’s network, some described in part in a recent paper authored by the company you'll find at this link: https://www.wexinc.com/wp-content/uploads/2025/09/WEX-Closed-Loop-Fleet-Card-White-Paper.pdf

But the human element in fraud prevention might be the biggest factor any size carrier can address to make the most gains in preventing losses, empowering themselves through self-education and passing that on to team members for those of you with more than just a single truck under your management. "We've seen the most yield" in fraud prevention, he said, "with education and empowerment."

Fitzgerald described efforts of Wex to illustrate the kinds of schemes that might result in infiltration of its own backend, including simulated phishing attacks through targeted fake emails designed to get a user to provide access to their login data with a goal of compromising accounts. Wex sends such emails to its own employees on occasion to lure them in, thus serving an educational purpose in awareness. Their most "successful" such an effort? An offer of "free Taylor Swift tickets. Everybody clicked on that," Fitzgerald said.

In the podcast, track through Fitzgerald's entire NASTC talk, tracking through those backend upgrades but also plenty more you can do to work with the company's team and tools in its system, like its SecureFuel solution, to prevent fuel theft. Likewise, should the worst, to work with law enforcement to apprehend the thieves.
