ATM skimming uses a device attached to or hidden inside a card reader to copy magnetic-stripe data; a separate camera or false keypad may capture the PIN. Banks sometimes spot skimming devices or resulting fraud, but detection is not guaranteed. A quick visual check, PIN shielding, chip use where available, and prompt account monitoring can reduce risk without proving an ATM is safe.
How ATM skimming works
A physical skimmer is fitted over or inside an ATM’s card reader to copy information from the card’s magnetic stripe. The customer may complete a normal-looking transaction without noticing anything unusual. Criminals can use the copied information to make counterfeit cards and attempt unauthorized withdrawals. The FBI describes the method in its ATM skimming overview, and Europol discusses it in its payment-fraud assessment.
Capturing the PIN is a separate step. A concealed camera may record keypad entry, or a false keypad may capture what the customer types. Card data without the PIN and PIN exposure are distinct risks, which is why shielding the keypad matters even if the reader itself looks ordinary.
Skimming is not the same as an ATM software attack
Skimming usually refers to copying card data with a physical reader device. Europol also describes malware that targets ATM software, jackpotting attacks that make a machine dispense cash, and black-box attacks that manipulate ATM functions. These are different attack methods, not simply variations of a reader overlay.

Can banks detect ATM skimmers?
Sometimes, but there is no basis for saying every bank detects every skimmer or uses one universal detection method. In a case described by the FBI, some banks noticed installed devices promptly, while other customers’ accounts were drained. That account is an example, not a measure of detection rates across banks.
Europol’s 2016 threat assessment warns that deep-insert skimmers can evade standard protections and detection measures and may be invisible to ATM users. The public sources cited here do not establish which signals every bank monitors or how reliably a particular bank identifies a device. Banks may discover a problem through a device inspection or after suspicious transactions, but a customer should not treat bank detection as assured.

How to check an ATM and reduce your risk
- Inspect the card reader and keypad. Look for loose, crooked, damaged or scratched parts, or anything that appears added or out of place. The FBI’s skimming guidance recommends checking for these signs. If something seems suspicious, do not use the machine. A normal appearance is not proof that a concealed or deep-insert device is absent.
- Cover the keypad while entering your PIN. Use your other hand to block the view of a camera or anyone nearby.
- Choose a practical location. Prefer a well-lit, indoor ATM when practical. Location can affect exposure, but it does not guarantee that a machine is safe.
- Use chip transactions when available. Chip use improves protection during a chip transaction. A chip card’s magnetic stripe remains vulnerable if a transaction falls back to stripe reading. The FBI explains this distinction in its guidance on chip-card vulnerabilities.
- Keep an eye on account activity. Review transactions and enable account or transaction alerts if your issuer offers them. Alerts help you notice possible misuse; they do not prevent a skimmer from copying card data.
What to do if an ATM keeps your card or you spot an unauthorized transaction
- Contact your card issuer promptly. Use the number on your card or the issuer’s official app or website. Report a retained card or transaction you did not authorize and follow the issuer’s instructions about blocking or replacing the card.
- Report suspected skimming. The FBI directs skimming reports to the Internet Crime Complaint Center. If the machine is at a bank or business, notify its staff as well, but do not handle a suspicious attachment.
