How to Tell if an ATM Has a Skimmer?
Safeguard your financial data. Understand key indicators to detect hidden card-skimming devices at ATMs and prevent fraud.
An ATM skimmer is an illicit device criminals attach to automated teller machines to steal payment card data. These devices are designed to appear as a normal part of the ATM. Skimmers typically capture card numbers, expiration dates, and sometimes the Card Verification Value (CVV), while associated hidden cameras or keypad overlays record Personal Identification Numbers (PINs).
Identifying Suspicious Physical Features
A visual inspection of an ATM can reveal indications of a skimmer. Observe the card reader slot for unusual bulkiness, a different color or material, or signs of adhesive. The card reader might also appear misaligned, crooked, or stick out more than usual. Some skimmers, known as “shimmers,” are very thin and inserted directly into the card reader.
Examine the keypad for signs of an overlay, such as a raised or unusually thick appearance. The buttons might feel stiff, hard to press, or have a spongy feel, indicating a fake keypad placed over the real one. Look for inconsistencies in texture or material between the keypad and the surrounding ATM.
Hidden cameras may be placed in inconspicuous locations to record PIN entries. These can be found above the screen, near the keypad, on side panels, or disguised within brochure holders or light fixtures. Any unusual attachments or panels that seem out of place, poorly fitted, or have visible glue or tape residue should raise suspicion. Compare the ATM’s appearance to a known legitimate ATM, or to other ATMs nearby, to spot inconsistencies.
Testing for Tampering
After a visual inspection, physical checks can help confirm a skimmer. Perform a “wiggle test” on the card reader by gently pulling or wiggling its parts. Legitimate card reader components are firmly attached and should not move or come loose. If any part of the card reader jiggles or feels loose, it suggests tampering.
Check the keypad by pressing down on its corners or edges to determine if it lifts or feels loose. A keypad overlay may not be securely affixed and could indicate a skimmer. Gently push or pull on panels around the screen or card slot to see if they are loose or can be removed, as skimmers can sometimes be part of larger false fronts. Pay attention to how your card fits into the slot; if it feels unusually tight or loose, or if there is resistance, this could be a sign of a skimmer.
Responding to a Suspected Skimmer
If you suspect an ATM skimmer, avoid using the machine and move away immediately. Do not attempt to remove the device yourself, as this could be dangerous or destroy valuable evidence. Instead, promptly report the suspicious activity.
Contact the bank that owns the ATM directly; their phone number may be displayed on the machine or nearby signage. If the bank is closed, or you are unsure who owns the ATM, contact local law enforcement. When reporting, provide specific details such as the ATM’s exact location, time of observation, and a clear description of what you noticed. This information assists authorities in their investigation and helps prevent further incidents.
Monitoring Your Accounts
Regularly checking your financial accounts helps mitigate potential fraud, regardless of whether you suspect a skimmer. Review your bank and credit card statements frequently for unauthorized transactions, even small ones, as criminals may test cards with minor charges before attempting larger ones. Many financial institutions offer transaction alerts that can notify you by text or email of activity such as withdrawals, purchases, or unusual account changes. Setting up these alerts can help you detect and respond to fraudulent activity quickly.
Periodically reviewing your credit reports from the major credit bureaus (Equifax, Experian, TransUnion) can help identify suspicious new accounts or inquiries opened in your name. Many services offer free credit monitoring or alerts for significant changes. If you discover fraudulent activity, report it to your bank immediately; most banks have fraud departments that can assist in cancelling compromised cards and disputing unauthorized charges. Understanding your bank’s fraud liability policies is important, as federal laws often protect consumers from significant losses if fraud is reported promptly.
