Credit cards have become an essential part of our daily lives. Today, virtually everyone has at least one card to make purchases. But one problem that can arise is having your credit card cloned.

Therefore, in this article, we'll show you what can happen when a credit card is cloned, what to do in this situation, and how to avoid this type of problem. Read the article to the end and learn everything about the subject. 

What does it mean if a credit card has been cloned?

When we say a credit card has been cloned, it means someone has managed to obtain credit card information without authorization and create an unauthorized copy of it. This copy, known as a "clone," contains the same data as the original card, including the card number, expiration date, and security code.

Once a credit card has been cloned, criminals can use it to make fraudulent purchases online or in physical stores, or even to withdraw cash from ATMs, depending on the features available on the card.

In other words, if your card has been cloned, you may be paying bills for other people who are using your card to make purchases in your name.

My card was cloned: what should I do?

If you suspect your credit card has been cloned, it's important to take immediate action to protect your account and minimize any financial losses. Here are the steps you should take:

  • Contact your financial institution: Call the customer service number provided by your financial institution, usually found on the back of your card. Inform them that you suspect your card has been cloned and follow their specific instructions.
  • Block the card: Ask the financial institution to block or cancel the affected card immediately. This will prevent criminals from continuing to use the card to make fraudulent transactions.
  • Review transactions: Ask your financial institution for a detailed history of recent transactions made with your card. Review it carefully to identify any unauthorized transactions. Record all suspicious transactions, including the dates, amounts, and establishments where they were made.
  • File a police report: Go to a police station and file a report about your card being cloned. Provide all relevant details, including the fraudulent transactions, if any.
  • Update your passwords and information: If the cloned card is linked to online accounts, such as payment services or recurring purchases, update the passwords for those accounts immediately. Also, notify other financial institutions where you have accounts so they can be aware of the cloned card and take additional precautions.
  • Monitor your accounts: Be alert to any suspicious activity in your financial accounts. Regularly review your bank statements, credit card statements, and other financial records to identify any unauthorized transactions. If you notice anything unusual, report it immediately to your financial institution.
  • Protect yourself from future cloning: To avoid future cloning, be cautious when sharing personal and financial information. Avoid providing credit card details on unsecured websites and be aware of potential phishing scams. Also consider monitoring your credit history regularly to detect any suspicious activity.

When the card is cloned, who pays the bill?

When a credit card is cloned and fraudulent transactions occur, the cardholder is not responsible for the illicit expenses. The responsibility falls on the card issuer, as cloning is considered a company error. Even if the invoice has already been paid, it is possible to request a refund for the unrecognized amount.

When reporting cloning to the operator, they will verify that the cardholder didn't make the purchase based on the transaction details, such as the location. If the purchase occurred in a city far from home, it will be easier to prove. Online purchases sent to other addresses are also ways to prove card cloning.

The carrier is required to issue a new invoice, excluding all unrecognized debts. In some cases, the process may take some time if the company needs to conduct a detailed analysis of the case. 

However, not all situations are straightforward, and in some cases, the operator may ask the cardholder to prove that the purchases were not made by them. Fortunately, most procedures for deleting expenses from the invoice are straightforward and resolve the issue for the customer.

How is a credit card cloned? 

A credit card can be cloned in several ways. Here are some of the main techniques used by criminals:

  • Skimming: This is a common method in which criminals install illegal devices in ATMs, payment terminals, or other card-reading devices. These devices are designed to copy card information, such as the number, expiration date, and security code, when the card is inserted.
  • Phishing: Scammers send fake emails, text messages, or make phone calls pretending to be legitimate financial institutions or businesses. They attempt to trick users into providing their personal information, including credit card details.
  • Physical theft: Criminals can physically steal a person's credit card through theft or by breaking into their home or workplace. They then use the card to make fraudulent purchases before the cardholder realizes it's missing.
  • Data interception: During unsecured online transactions, credit card data can be intercepted by hackers. This can happen when the website lacks adequate encryption or when the user enters their information on unsecured public Wi-Fi networks.
  • Data breaches: When security breaches occur in companies or institutions that store credit card information, card data can be stolen and used for cloning. These breaches can occur due to system security flaws or hacker actions.

It's important to be aware of these threats and take steps to protect your credit card information. This includes being cautious when providing personal information online, checking the security of the websites you use to conduct transactions, and regularly monitoring your account activity to identify any suspicious activity.

How do I know if my credit card has been cloned?

There are some signs and indicators that can help you identify if your credit card has been cloned. Here are some things to look for:

  • Unknown transactions: Carefully review your credit card statement or invoice. Look for transactions you don't recognize or haven't authorized. This includes purchases at unfamiliar establishments or locations you haven't been to, as well as duplicate charges.
  • Bank notifications: Pay attention to any messages, emails, or notifications you receive from your bank or financial institution. They often send alerts about suspicious activity in your account, such as unusual or suspicious transactions.
  • Unsolicited confirmation messages: If you receive confirmation messages for purchases you didn't make or account confirmation emails from unfamiliar websites, it could be a sign that your card has been cloned and used to make fraudulent transactions.
  • Card usage issues: If your card is suddenly declined at establishments where it was previously accepted, this may indicate that the original card has been blocked due to suspicious activity and cloning may have occurred.
  • Suspicious messages or phone calls: Be wary of suspicious text messages, emails, or phone calls requesting personal information, such as credit card details. Scammers may attempt to obtain your sensitive data through phishing methods.

What are the tips to avoid having your credit card cloned?

There are several steps you can take to reduce the risk of having your credit card cloned. Here are some tips to avoid credit card cloning:

  • Keep your information safe: Never share your credit card information via email, phone, or text message unless you're dealing directly with a trusted and secure source. Avoid providing your information on unsecured or unknown websites.
  • Check website security: When making online transactions, make sure the website is secure. Look for the padlock icon in your browser's address bar and check if the address begins with "https" instead of just "http." This indicates that the connection is encrypted and more secure.
  • Be careful with public Wi-Fi networks: Avoid making financial transactions or providing sensitive credit card information on public or unsecured Wi-Fi networks. These networks can be targeted by hackers who can intercept your data.
  • Protect your passwords: Use strong, unique passwords for your online accounts. Avoid using obvious information, such as birth dates or simple number sequences. Also, don't share your passwords with others and change them regularly.
  • Monitor your accounts regularly: Keep an eye on activity on your financial accounts, including credit cards. Regularly review your bank statements, credit card statements, and other financial information to identify any suspicious or unrecognized transactions.
  • Protect your card physically: Keep your credit card in a safe place and avoid leaving it unattended. Don't lend your card to third parties and never let it out of your sight during transactions in stores or restaurants.
  • Be aware of phishing scams: Be alert to suspicious emails, text messages, or phone calls requesting personal or financial information. Never click on suspicious links or provide sensitive information without verifying the authenticity of the source.
  • Keep your software up to date: Keep your device (computer, phone, tablet) and apps updated with the latest security updates. This helps protect against known vulnerabilities that hackers can exploit.
