What to check first (before you act)

Your Credit Card Security Habits

Before implementing new measures, take stock of your current practices. Are you in the habit of checking your statements regularly? Do you use ATMs in well-lit, public areas? Understanding your current behavior is the first step to identifying areas for improvement.

Your Credit Card Issuer’s Security Features

Most credit card companies offer built-in security tools. Familiarize yourself with what your issuer provides, such as fraud alerts, transaction notifications, and options for temporary card deactivation. Knowing these features can empower you to use them effectively.

Your Awareness of Skimming Tactics

Skimming involves devices that steal card information during legitimate transactions. This can happen at gas pumps, ATMs, or even point-of-sale terminals. Being aware of common skimming methods helps you spot potential threats in real-time.

Step-by-step (simple workflow)

1. Inspect Payment Terminals

What to do: Before inserting or swiping your card, visually inspect the payment terminal. Look for anything that seems loose, damaged, or out of place. Gently tug on the card reader to see if it feels secure.
What “good” looks like: The terminal is securely attached, has no visible signs of tampering, and all parts appear to be original.
A common mistake and how to avoid it: Assuming all terminals are safe. Avoid this by making inspection a routine part of every transaction, even if you’re in a hurry.

2. Prioritize Contactless Payments

What to do: Whenever possible, use “tap to pay” or mobile payment apps (like Apple Pay or Google Pay) linked to your credit card. These methods use tokenization, which encrypts your card number.
What “good” looks like: You consistently opt for contactless payment options at merchants that support them.
A common mistake and how to avoid it: Sticking to swiping or inserting out of habit. Avoid this by actively looking for the contactless symbol and choosing it when available.

3. Guard Your PIN

What to do: When entering your Personal Identification Number (PIN), shield the keypad with your other hand or a bill. This prevents anyone from observing your PIN, whether they are physically present or using a hidden camera.
What “good” looks like: You consistently cover the keypad when entering your PIN, making it impossible for onlookers to see.
A common mistake and how to avoid it: Forgetting to shield the keypad, especially in familiar or seemingly safe environments. Avoid this by treating every PIN entry as a potential security risk.

4. Use Reputable ATMs and Gas Pumps

What to do: Whenever possible, use ATMs inside banks or in well-lit, high-traffic areas. For gas pumps, choose those that appear well-maintained and free of suspicious attachments.
What “good” looks like: You primarily use ATMs and gas pumps that are known for their security and good condition.
A common mistake and how to avoid it: Using any available ATM or gas pump without consideration for its security. Avoid this by planning ahead and seeking out more secure options, even if it means a slight detour.

5. Enable Transaction Alerts

What to do: Log in to your credit card account online or through the mobile app and set up real-time transaction alerts. These can notify you via text or email for purchases above a certain amount or for any transaction.
What “good” looks like: You receive immediate notifications for your credit card activity, allowing for quick detection of unauthorized charges.
A common mistake and how to avoid it: Not setting up alerts or ignoring them. Avoid this by actively configuring these alerts and treating them as critical security information.

6. Review Statements Diligently

What to do: Make it a habit to review your credit card statements thoroughly at least once a month, or more frequently if you receive alerts. Look for any charges you don’t recognize.
What “good” looks like: You can account for every transaction on your statement and immediately report any discrepancies.
A common mistake and how to avoid it: Quickly glancing at statements or assuming all charges are correct. Avoid this by dedicating time to a detailed review and knowing what constitutes an unrecognized charge.

7. Secure Your Physical Cards

What to do: Keep your credit cards in a secure wallet or cardholder. Never leave them unattended, and report lost or stolen cards to your issuer immediately.
What “good” looks like: Your cards are always in your possession or a secure location, and you know who to contact if they go missing.
A common mistake and how to avoid it: Being careless with your cards, leaving them in a car or easily accessible public places. Avoid this by being mindful of your cards’ whereabouts at all times.

8. Consider a Credit Freeze

What to do: If you believe your information has been compromised or you want an extra layer of security, consider placing a credit freeze with the three major credit bureaus (Equifax, Experian, and TransUnion). This prevents new credit accounts from being opened in your name.
What “good” looks like: You have peace of mind knowing that new credit applications will be blocked without your explicit permission.
A common mistake and how to avoid it: Waiting until after a fraudulent incident to consider a freeze. Avoid this by proactively placing a freeze if you have significant concerns about data security.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not inspecting payment terminals	Skimmers can be attached unnoticed, leading to the theft of your card number, expiration date, and CVV.	Make inspecting terminals a mandatory step before every transaction. Look for loose parts or unusual attachments.
Relying solely on swiping/inserting	These methods are more vulnerable to skimming devices than contactless options, which use tokenization.	Prioritize “tap to pay” or mobile wallet payments whenever possible.
Not shielding the PIN keypad	Your PIN can be easily observed by onlookers or captured by hidden cameras, allowing fraudsters to make unauthorized purchases.	Always cover the keypad with your hand or a bill when entering your PIN.
Using unsecured or unfamiliar ATMs/gas pumps	These locations are prime targets for skimmers. Compromised machines can steal your card data and even record your PIN.	Stick to ATMs in secure locations (like inside banks) and well-maintained gas pumps. If a pump looks suspicious, don’t use it.
Ignoring transaction alerts	You might miss early signs of fraudulent activity, allowing thieves to rack up significant charges before you notice.	Set up and actively monitor transaction alerts from your credit card issuer. Treat them as urgent security notifications.
Infrequent or superficial statement reviews	Unauthorized transactions can go unnoticed for extended periods, making it harder to dispute them and potentially leading to further fraud.	Review your credit card statements thoroughly at least once a month. Look for any charges you don’t recognize.
Leaving cards unattended	Lost or stolen cards can be used for immediate fraudulent purchases, especially if the thief knows your PIN or can bypass signature checks.	Always keep your credit cards secure and in your possession. Report lost or stolen cards to your issuer immediately.
Not reporting suspicious devices promptly	Failing to report a suspected skimmer allows it to continue to defraud others.	If you see a suspicious device on a payment terminal or ATM, report it to the merchant or the bank operating the ATM.
Not using credit freezes when concerned	If your personal data has been compromised in a breach, your cards are at higher risk of being used fraudulently for new accounts.	Consider placing a credit freeze with the major credit bureaus if you’re concerned about identity theft or a data breach.
Assuming your issuer will always catch fraud	While issuers have fraud detection, it’s not foolproof. Proactive steps are crucial for immediate protection.	Don’t rely solely on your issuer. Be an active participant in protecting your card information.

Decision rules (simple if/then)

• If you see a loose or damaged part on a payment terminal, then do not use it because it might have a skimmer attached.
• If a merchant offers contactless payment, then use it because it offers enhanced security through tokenization.
• If you are entering your PIN at an ATM or payment terminal, then shield the keypad because this prevents others from seeing your PIN.
• If you are at an unfamiliar ATM, then check for any unusual attachments around the card slot or keypad because these could be skimmers.
• If you receive a transaction alert for a purchase you didn’t make, then immediately contact your credit card issuer because this is likely fraudulent activity.
• If your credit card statement shows a charge you don’t recognize, then dispute it with your issuer immediately because prompt action is crucial for resolution.
• If your credit card is lost or stolen, then report it to your issuer without delay because this limits your liability for fraudulent charges.
• If you’ve been a victim of a data breach, then consider placing a credit freeze because this protects against the opening of new fraudulent accounts in your name.
• If you are in a public place and need to use a credit card, then choose a terminal that is well-lit and in plain view because these are less likely to be tampered with.
• If you are asked to swipe your card when a chip or contactless option is available, then question the need to swipe because it’s a less secure method.
• If you are using a gas pump, then inspect it for any odd devices attached to the card reader before inserting your card because gas pumps are common targets for skimmers.
• If you are unsure about the security of a payment terminal, then use cash or a different payment method because it’s better to be safe than sorry.

FAQ

What is credit card skimming?

Credit card skimming is a form of electronic theft where criminals attach devices to legitimate payment terminals or ATMs to illegally capture your credit card information, including your card number, expiration date, and CVV.

How can I tell if a credit card reader has a skimmer?

Look for anything that seems loose, poorly fitted, or out of place on the card reader. Sometimes skimmers are disguised to look like part of the original device, but they may have different colors or textures. Gently tugging on the reader can sometimes reveal if it’s a fake attachment.

Are contactless payments (like Apple Pay or Google Pay) safe from skimming?

Yes, contactless payments are generally safer from traditional skimming because they use tokenization. Instead of transmitting your actual card number, a unique, encrypted code is used for each transaction, making it much harder for thieves to steal your sensitive data.

What should I do if I find a skimmer?

If you suspect a skimmer, do not use the terminal. Take a photo of it if possible without touching it, and report it immediately to the merchant or the financial institution that owns the ATM.

How often should I check my credit card statements?

It’s best to check your credit card statements at least once a month. However, if you have set up transaction alerts, you can monitor your account more frequently and catch suspicious activity almost in real-time.

What is the difference between a credit freeze and a fraud alert?

A credit freeze restricts access to your credit report, preventing anyone from opening new credit accounts in your name without your explicit permission. A fraud alert, on the other hand, warns potential creditors to verify your identity before extending credit. A freeze offers stronger protection.

Can I get my money back if my credit card is skimmed?

Yes, under federal law (Fair Credit Billing Act), your liability for unauthorized charges is limited to $50 if you report the loss or theft promptly. Most credit card companies offer zero liability for fraudulent transactions, meaning you won’t be responsible for any unauthorized charges if reported quickly.

Are gas pumps more vulnerable to skimming than other payment methods?

Yes, gas pumps are frequent targets for skimmers because they are often less monitored and have more exposed card readers. It’s crucial to inspect gas pump card readers carefully before use.
