Understanding Credit Card Cloning

Credit card cloning, a term that often brings to mind biological experiments or science fiction, is a serious and everyday problem for consumers. This process involves the creation of fraudulent copies of credit cards, which can lead to unauthorized transactions and financial losses. Understanding how credit card cloning works and knowing how to prevent it can help protect your financial security.

What is a Counterfeit Credit Card?

A counterfeit credit card is a fake card that contains real credit card information, involving a steal of the victim's data. The card information is often encoded with magnetic strips and includes the logos of the credit card issuer. While it may sound like something straight out of a movie, credit card cloning is a very real threat.

How Does Credit Card Cloning Work?

There are two major steps in the process of credit card cloning: obtaining the credit card information and creating a fake card for use in purchases. Here’s a detailed look at each step:

Stealing Credit Card Information

The first step involves the theft of credit card details, including the cardholder's name, credit card number, and expiration date. This information is often acquired through skimming or shimming.

Skimming

Skimming is a common method where thieves use devices to copy credit card information. This typically happens at gas pumps or ATMs, but can also occur when you hand over your card for payment and it leaves your sight. For example, a wait staff member might use a handheld device to skim your credit card data.

In a typical skimming scam, a crook attaches a device to a card reader, which allows them to electronically copy or skim data from the magnetic strip on the back of the card. This magnetized data is then used to create a fraudulent copy of the credit card.

Shimming

Shimming is a similar method that involves stealing information from chip-enabled credit cards. According to credit bureau Experian, this is achieved by inserting a thin device into a slot on a card reader that accepts chip-enabled cards. This device is equipped with a microchip and flash storage, allowing it to copy data from your credit card. While this data can't be used to clone another chip-enabled card, it can create a magnetic-strip version for use in fraudulent transactions.

Creating a Cloned Credit Card

With the stolen data, crooks use credit card cloning machines to create new, fake cards. They may also change the name on the card to make it appear legitimate. These cards are then used for fraudulent purchases, often in large volumes. Any non-functional cards are typically discarded as thieves move on to the next card.

How Big of a Problem Is Credit Card Cloning?

The production and use of cloned credit cards are concerning, especially for U.S. consumers. However, the rate of these fraudulent activities is declining. According to Visa in 2018, financial losses related to counterfeit fraud had dropped 46% at all U.S. merchants by March 2018 compared to September 2015. Chip-enabled card readers significantly reduce the risk of in-person point-of-sale transactions being compromised.

How to Reduce Your Risk of Credit Card Cloning

To minimize the risk of falling victim to credit card cloning, it's crucial to adopt certain protective measures:

Look Out for Skimmers and Shimmers

Before inserting your card into a gas pump, ATM, or card reader, be cautious. Check for any visible damage, loose equipment, or other signs that a skimmer or shimmer may have been installed. If you’re using a card at a gas pump, the Federal Trade Commission recommends looking for security seals that have been broken or pulling on the card reader to ensure it's not loose.

Use Chip-Enabled Cards

Chip cards, also known as EMV (Europay, Mastercard, Visa) cards, are more secure because they generate a one-time transaction code each time they are used. This code makes it harder for fraudsters to duplicate the card. Despite the added security, chip cards still have magnetic strips, ensuring compatibility with older point-of-sale systems.

Purchase with Mobile Payment Apps

Mobile payment apps provide a safer alternative to physical cards. With digital transactions, the data transmitted is far less likely to be compromised compared to magnetic strips on physical cards.

Pay with Cash

Using cash for transactions avoids the hassles and potential financial risks that can arise when using credit cards. While inconvenient, cash transactions offer a layer of security against cloning attempts.

Monitor Your Credit Card Activity

Regularly check your credit card statements and set up alerts for significant transactions. If you notice any suspicious activity, such as purchases in unfamiliar locations or at unexpected times, notify your card issuer immediately to deactivate your card and prevent further fraudulent charges.

Legal Protection

Under the federal Fair Credit Billing Act, if you notice unauthorized activity on your credit card, you are not financially liable for the unauthorized charges. However, it's still important to report it to your card issuer as quickly as possible.
