Fuel card security: Identifying 4 common scam indicators

Someone can drain your fuel card while your truck is parked. They don’t even need your card to do it.

A skimmer on the pump, a camera pointed at the keypad, and your card data is gone before you pull back onto the highway. By the time you check your statement, there are charges in cities you’ve never driven through.

For owner-operators, that kind of loss comes straight out of operating cash. With fuel pricing already putting pressure on margins, there’s no buffer to absorb unauthorized charges while a dispute gets sorted out. Knowing how fuel card fraud works, and what to watch for, is one of the more direct ways to protect what you’ve earned.

This article covers the main types of fuel card fraud, four red flags, how technology can surface suspicious activity early, and concrete steps to protect your business.

Types of fuel card fraud

Fuel card fraud takes many forms, and the methods keep changing. Knowing what you’re up against is the first step toward catching it early. For owner-operators, keeping a close watch on fuel spend is part of effective fuel management for your operation, and that starts with understanding where the exposure is.

• Fuel card cloning occurs when a scammer copies your card data and uses it to make unauthorized purchases elsewhere. Card information gets lifted through hacked accounts, mail theft, or someone photographing your card when you’re not paying attention.
• Fuel card skimming involves a device installed on a pump’s card reader that records your magnetic strip data as you swipe. Skimmers often come with additions: a hidden camera aimed at the keypad to capture your PIN, or a false keyboard overlay placed directly over the real one.
• Identity theft via phishing or smishing happens when scammers trick you into giving up personal information through a fake email (phishing) or a fraudulent text message (smishing). Once they have your login credentials, they can access your account directly without ever touching your card.
• Lost or stolen cards are one of the most common starting points for fraud. A misplaced card gets picked up and used within minutes, often before you realize it’s gone and can get it frozen.
• Internal fraud and slippage can happen even in a one-driver operation. Slippage means using the card for more than the route requires: filling an extra container, buying provisions at the pump, or claiming a higher fuel allowance than what was actually needed. It tends to start small and adds up quietly over time.
• Compromised contactless payment devices are a more targeted approach. Scammers drill holes into a pump’s contactless screen, making it unusable. Drivers are then forced to swipe their card directly into a skimmer the scammer has already installed on the reader below.

These threats cover a wide range, from skimmers at the pump to phishing texts to slippage inside your own cab. Knowing what each one looks like is the foundation for catching it early, and when you’re weighing fuel card options for owner-operators, the security controls a program offers are worth as much attention as the discount rates.

4 red flags to watch at the pump and in your statements

Preventing fraud means recognizing specific signals, not just a general sense that something seems off. These four indicators should prompt an immediate review.

1. Unusual transactions. Any charge on your fuel card statement that’s off your route, in the wrong location, or at an amount you can’t account for is worth investigating. If you can’t place the transaction, don’t wait until next month’s statement to follow up.

2. Multiple transactions in a short time. Keep a record of every stop: when you fueled, how many gallons, and where. If your statement shows more fill-ups than your route required, that gap needs an explanation. More charges than the trip called for is a consistent pattern in fuel card fraud.

3. Suspicious activity at the pump. Before you swipe, take a look at the card reader. A cracked casing, a keypad that doesn’t sit flush, or a contactless screen that’s been drilled out and won’t respond are all signs the reader may have been tampered with. If something looks off compared to the other pumps at the same station, move to a different pump or a different location entirely.

4. Receipts that don’t match. Get a receipt every time you fuel, then check it against your statement line by line. Even a small discrepancy can indicate a skimmer adding a charge that’s small enough to go unnoticed. Any statement line without a corresponding receipt attached to it deserves a call to your card provider.

Beyond those four, there are a few additional patterns worth building into your routine review:

• Transactions that posted outside of normal working hours
• A fuel type charged that doesn’t match what your truck actually runs on
• Fuel costs that don’t line up with the miles you drove or your tank’s actual capacity

None of these automatically confirm fraud, but when any of them show up alongside one of the four indicators above, contact your card provider the same day and start pulling receipts.

How technology can help prevent fuel card fraud

Your fuel card’s built-in analytics are one of the most practical tools for catching fraud early. Most programs monitor spending patterns and flag unusual activity automatically, so if your weekly spend jumps or a charge appears in an unexpected city, you get an alert before the damage adds up.

Truckstop’s Fuel Card takes that a step further by giving you the ability to lock or freeze a specific card immediately when something looks off, without waiting on a fraud investigation to move first.

ELD apps with built-in telematics map fuel purchases against your actual location. If a charge shows up at a station you never stopped at, or on a road that wasn’t part of your route, that location data gives you something concrete to bring to your card provider.

How to protect your trucking company from fuel card fraud

Technology helps you catch fraud. These four steps help you prevent it. Keeping fuel costs predictable, whether through furthering your fuel economy on every run or capping what each card can spend, comes down to the same principle: knowing exactly what’s going out and why.

Require a unique PIN for every driver. Every person using a card in your operation should have their own PIN. It should never be shared or written down anywhere in the cab. Remind drivers to shield the keypad when entering it, especially at busy truck stops where someone nearby may be watching.

Set daily spending limits. Most fuel card programs let you cap how much can be spent per day per card. Calculate a realistic ceiling based on route length and current fuel prices, then set each card to that number. If a card gets skimmed, the total damage is capped. If slippage is creeping in internally, it gets stopped at that same limit.

Understanding how fuel surcharge rates factor into your per-mile costs helps you set those limits accurately without cutting a driver short on a legitimate run.

Restrict fueling to working hours. Off-hours transactions are one of the clearest signals in fraud cases. If your statement shows a fill-up at 2 a.m. and your truck was sitting at a rest area, that warrants an immediate call to your card provider. Setting card access to working hours only closes a window that scammers and drivers with loose habits have consistently relied on.

Educate your drivers. If you run with other drivers or rotate routes, make sure they know what a skimmer looks like, how phishing and smishing scams work. Make clear that internal misuse, including slippage, has real consequences. Most internal fraud doesn’t start as deliberate theft. It starts because the expectations were never spelled out clearly. A direct conversation upfront prevents most of those problems from developing.

How to stay ahead of fuel card fraud

Fuel card fraud doesn’t stay static. Skimming hardware keeps getting harder to spot, phishing texts get more convincing, and slippage tends to grow when oversight gets loose. The best defense is a combination of routine statement reviews, clear expectations for anyone who touches a card, and tools that flag unusual activity before it adds up to a real loss.

Truckstop’s Fuel Card gives owner-operators the spending visibility and account controls that make fraud harder to hide and faster to catch when it does happen.
