Whether you’re buying gifts online or in person, you need to be vigilant about protecting your cards from hackers and fraudsters who want to ruin your festive mood and steal your money and identity.

That’s why it’s important to follow some simple steps to keep your cards safe and secure, no matter where or how you shop.

How to keep your cards and data secure when using your card in person

Your card is a valuable tool for making payments, but it also carries some risks. Fraudsters can use various methods to steal your card information or PIN and use it for unauthorized transactions. To prevent this, you need to take some precautions when using your card in person. Here are some tips to help you protect your cards and data from fraud.

Protect your PIN

Your Personal Identification Number (PIN) is the gateway to your funds. Never share your PIN with anyone or write it down where it can be easily discovered. Always cover the keypad while entering your PIN. Be cautious of skimming devices attached to ATMs, which can stealthily capture your card information.

Be alert and aware

When using your card in person, be aware of your surroundings and watch out for any signs of tampering or skimming on the card reader. If something looks suspicious, do not use the card reader and report it to the merchant or the authorities. Also, be careful of anyone who tries to distract you or offer you help while you are using your card. They may be trying to steal your card or PIN. There is an increased risk of card theft, and fraud is higher in certain places like gas stations, restaurants, and bars.

Travel safely

Some banks no longer require travel notices thanks to improved fraud detection systems, but notifying your bank before a trip can still help prevent unexpected account holds. Keep your cards in a secure location and avoid displaying them in public.

Use contactless payments

Contactless payments are a convenient and secure way to pay with your card without inserting it into a terminal or handing it over to a cashier. You can use your card, smartphone, or wearable device to tap and pay at participating merchants. These payments are secure because they use encryption and tokenization, which replace your actual card number with a temporary code during transactions.

Use a chip over a magnetic strip

Whenever possible, opt for using the chip on your card rather than the magnetic strip. Chip technology offers enhanced security against cloning and fraud.

Opt for using an RFID credit card

RFID credit cards, also called contactless or tap-to-pay cards, come equipped with a tag for contactless payments. These cards are generally safe to use because modern systems rely on tokenization and built-in security protections, not just the RFID signal itself.

The scanner emits radio waves that pick up signals from nearby items with RFID tags, which also send out radio waves. While concerns about wireless scanning exist, real-world cases of this type of fraud are extremely rare. RFID cards can best be protected by keeping the cards either in a sleeve or keeping the cards in an RFID-protecting wallet or case. Some people choose RFID-blocking wallets for added peace of mind, although they are not essential for most users. You’ll usually be able to tell if a credit card is RFID-enabled by the contactless symbol on the front or back of the card. It looks like a sideways Wi-Fi symbol.

How to protect your card and personal information online

Use strong passwords

Use a combination of letters, numbers, and symbols for your online accounts and change them regularly. Avoid using the same password for multiple accounts or websites. Consider using a password manager to store and generate secure passwords.

Shop securely

When shopping online, look for the padlock icon or “https” in the address bar of your browser, which indicates that the website is secure. Use a credit card or a reputable payment service that offers fraud protection. For even more protection, consider using virtual card numbers when available, which generate temporary card details for each transaction. Avoid using public Wi-Fi or computers to make online transactions.

Use card features

Many banks offer card features that allow you to control and monitor your card’s usage. Set up transaction alerts and notifications to stay informed about any unusual activity. Some banking apps also allow you to lock your card instantly or set spending limits for added control.

Consider an RFID-blocking wallet

While rare, some forms of wireless scanning are theoretically possible, and RFID-blocking wallets can provide an extra layer of reassurance for those who want it. RFID-blocking wallets use a layer of aluminum or carbon fiber to make it more difficult for your card’s chip to be scanned without you knowing. Here are a few of my recommendations that get high ratings to help protect your credit cards from RFID readers.

Regularly monitor your account

Routinely review your bank and credit card statements to detect any unauthorized or suspicious transactions promptly. Report any discrepancies to your financial institution immediately.

Report lost or stolen cards immediately

In case your card is lost or stolen, report it to your bank or card issuer immediately to prevent unauthorized use. Most banks have 24/7 hotlines for this purpose.

Be cautious with emails and phone calls

Beware of phishing emails. Phishing is a fraudulent attempt to obtain your personal or financial information through emails, texts, or calls that appear to be from legitimate sources. Do not click on links or attachments from unknown or suspicious senders. Also, do not provide any sensitive information over the phone or online unless you are sure of the identity and authenticity of the requester.

Have strong antivirus software on all your devices

Strong antivirus software is a helpful layer of protection that can detect malicious downloads, warn you about dangerous links, and identify suspicious behavior on your device. However, it should be used alongside other safe habits, since many scams rely on tricking users rather than installing malware.

Don’t use credit cards online on public Wi-Fi

Public Wi-Fi can be risky, especially for sensitive transactions. Even though many websites use encryption, it’s still safer to use a secure, private network or a trusted VPN when accessing financial accounts.

How digital wallets can help to protect your financial information

Digital wallets such as Apple Pay, Google Pay, and Samsung Pay offer advanced security features to protect your financial information. These wallets store your payment options, including credit and debit cards, allowing you to use your smartphone or smartwatch for convenient and secure transactions.

They use Near Field Communication (NFC) technology to process payments, which is a secure way to transmit data between devices. NFC technology activates when you wave your digital wallet-enabled device in front of a contactless reader for a few seconds, ensuring secure payment processing.

These systems also rely on tokenization, meaning your actual card number is never shared with the merchant.

I’ve been scammed! What to do next?

Below are some next steps if you find you or your loved one is a victim of identity theft.

1) Secure your accounts immediately

If you can regain control of your accounts, change your passwords and inform the account provider.

2) Review your bank and card activity for suspicious charges

Look through bank statements and checking account transactions to see where outlier activity started.

3) Use an identity theft protection service

Identity Theft companies can monitor personal information like your Social Security Number (SSN), phone number, and email address and alert you if it is being sold on the dark web or being used to open an account. They can also assist you in freezing your bank and credit card accounts to prevent further unauthorized use by criminals.

4) Report identity theft to the FTC

Report identity theft to the Federal Trade Commission (FTC) at IdentityTheft.gov, which is the primary U.S. government resource for recovery steps and reporting.

5) Consider legal guidance if the situation escalates

You may wish to get the professional advice of a lawyer before speaking to law enforcement, especially when you are dealing with criminal identity theft, and if being a victim of criminal identity theft leaves you unable to secure employment or housing

6) Check your background for fraudulent activity

Run your own background check or request a copy of one if that is how you discovered your information has been used by a criminal.

7) Freeze your credit and place a fraud alert

Alert all three major credit bureaus – Equifax, TransUnion, and Experian. You can freeze or lock your credit report through their websites or dedicated apps. You’ll also want to place a fraud alert on your credit report.

If you are a victim of identity theft, the most important thing to do is to take immediate action to mitigate the damage and prevent further harm.
