ATMs make it easy to grab cash on the go, but they can also be targets for skimming devices and other types of fraud. Criminals only need a few seconds to steal your card details and PIN if you are not paying attention. This guide explains how ATM skimming works, how to spot tampered machines, and the simple habits that will help you keep your card and money safe.
What ATM Skimming and Card Fraud Look Like
ATM skimming happens when criminals install hidden devices on or inside an ATM to capture your card information and PIN. Once they have those details, they can clone your card or make unauthorized withdrawals. Skimming often works together with other tricks that target distracted users.
- Skimming overlays: Fake card readers placed over the real slot to read your card data.
- Hidden cameras: Tiny cameras aimed at the keypad to capture your PIN as you type.
- Fake keypads: Thin keypad covers that record your PIN presses.
- Card trapping: Devices that hold your card inside the ATM so thieves can retrieve it later.
- Distraction scams: People who crowd you, ask for help, or try to “assist” while watching your PIN.
Banks and ATM operators are constantly adding new defenses. To see how modern machines fight back, check out our guide to ATM anti-skimming technology and how EMV chip cards improve ATM security.
How To Spot a Tampered or Risky ATM
Most skimming setups leave small clues behind. Taking a few seconds to inspect the machine before you insert your card can make a big difference.
- Look for loose or bulky parts: Gently wiggle the card reader and keypad. If anything feels loose, misaligned, or cheaply attached, do not use that ATM.
- Check for extra plastic: Skimmers often add a second layer over the real card slot or keypad. If it looks thicker than usual, move on.
- Scan for tiny cameras: Look around the screen, card slot, and brochure holders for pinholes or unusual attachments that could hide a camera.
- Watch the screen behavior: If the screen flashes, restarts, or shows odd messages, cancel the transaction and remove your card.
- Trust your instincts: If anything about the ATM feels wrong or out of place, find another machine.
When in doubt, use machines in well-lit, monitored areas. Our guide to ATM sensors and cameras explains how built-in security features help protect you.
Smart Habits To Protect Your Card and PIN
You cannot control every ATM, but you can control your habits. These simple steps make it much harder for anyone to steal your information.
1. Always shield the keypad
Hidden cameras and shoulder surfers rely on a clear view of your PIN. Covering the keypad shuts them down.
- Use your free hand, wallet, or phone to shield the keypad while you enter your PIN.
- Stand close to the machine so it is harder for anyone to look over your shoulder.
2. Choose safer ATM locations
Some ATMs are simply higher risk than others. Skimmers are more likely to target machines that are easy to access and hard to monitor.
- Prefer ATMs located at bank branches, inside grocery stores, or in busy indoor areas.
- Avoid machines in dark corners, isolated parking lots, or places where people can easily stand behind you.
If you rely on accessible features like ramps or lower keypads, our guide on accessible ATMs explains how banks balance convenience and safety for more users.
3. Limit how long your card is in the machine
The longer your card sits in the reader, the more time a tampered device has to grab your data.
- Have your card ready before you approach the ATM so you are not fumbling at the machine.
- Complete your transaction promptly and put your card away before counting your cash.
4. Turn on account alerts and monitor activity
Even with careful habits, some fraud slips through. Real-time alerts can catch it early.
- Enable text or app alerts for ATM withdrawals and large transactions.
- Review your recent activity in your banking app at least once a week.
- Report any unfamiliar transaction right away, even if the amount is small.

What To Do If You Suspect Your Card Was Skimmed
If something feels off about the ATM, or you notice transactions you do not recognize, act quickly. Fast action can limit your losses and make it easier for your bank to help you.
- Stop using that ATM: Cancel the transaction if you can and remove your card immediately.
- Contact your bank right away: Call the number on the back of your card to report suspected fraud or a compromised machine.
- Freeze or replace your card: Many banking apps let you lock your card instantly. Ask for a new card and PIN if needed.
- Review recent transactions: Look for unfamiliar withdrawals or purchases and dispute them promptly.
- Follow up on disputes: Keep notes on dates, times, and reference numbers from your bank in case you need to escalate.

Technology That Helps You Stay Safer At ATMs
ATM security is not only about what you do as a customer. Modern machines and cards include built-in protections that make skimming harder and less profitable.
- EMV chip cards: Chip transactions generate one-time codes that are much harder to clone than traditional magstripe data. Learn more in our guide to EMV chip ATM security.
- Anti-skimming hardware: Many ATMs now have internal jamming devices and improved card readers designed to detect or block skimming overlays. See how they work in our overview of ATM anti-skimming technology.
- Cardless and contactless withdrawals: Some banks let you access cash with a mobile wallet or one-time code instead of inserting your physical card. Our guide to ATMs that work without a card explains how these options can reduce skimming risk.
