How Merchants Can Identify Fake Credit Cards

When credit card data is stolen, it is often used to create fake credit cards. This data is originally stolen from POSs and ATMs, and then sold online to criminals. These criminals can choose to purchase a local credit card number, paying for it by prepaid gift card, bitcoin, or wire transfer. Then, they can print the numbers onto fake credit cards.

These fake credit cards often don’t last for long. As soon as the bank is alerted to suspicious activities, the card account is frozen. However, in these hours, or days, before the bank freezes the account, criminals can use the card to make multiple purchases in store, or through online fraud. Frequently, criminals will choose to buy gift cards that can be redeemed for cash. When one account is frozen, the criminal can simply buy another stolen card number online.

One of the biggest challenges of online payments is fraud. Fraud, such as the use of fake credit cards, costs credit card companies and retailers large amounts of money. As a merchant, you should know how to identify a fake credit card, so that you can protect yourself from fraud. With this knowledge, you will be able to check credit cards while you are awaiting a payment authorization, identifying a suspicious card and avoiding the repercussions of a fraudulent payment.

Every credit card has a set of security features. If these features appear to be tampered with, or there are features that are missing completely, it’s possible the card is counterfeit. Here are the security features you should look out for to verify card authenticity.

General features

  • Cardholder name - Every credit card should have the cardholder name on the front. In most cases, the name is embossed.
  • Account number- On the front of each card, the account number should be clearly embossed and evenly spaced.
  • Magnetic stripe – The back of the card has a magnetic stripe that contains account information. This should be undamaged.
  • Signature field - The back of each card should have a signature field, and this should always be signed. Check that the signature matches the signature collected from the customer.

Here are some features that are particular to the most popular credit card brands:

MasterCard

  • Holographic magnetic stripe - A Centurion image hologram is featured on some but not all American Express card magnetic stripes.

  • Account number format - Discover account numbers are 16 digits long, beginning with a “6”.

These tips will allow you to identify fake credit cards by sight. There are additional steps to take when dealing with online payments, as you can’t physically check if a credit card is genuine.

You can verify that a credit card number is real by using the Luhn Formula, as follows:

  1. Double each odd digit of the card number.
  2. If any resulting sums are greater than 9, add the digits together e.g. 12 = 1+2.
  3. Add up all the resulting digits from step 2, with all digits from step 1 that were under 9, and the even numbers from the original card number.
  4. If the total ends in a 0, the number is valid.

However, a stolen number would still come up as valid, according to the Luhn formula. This is why it’s important to work with a PCI DSS certified PSP, such as Direct Pay Online, so you can process secure online payments without fear of fraud.

Now that you know the signs of a fake credit card or credit card number, you can prevent fraudulent transactions from taking place and protect your business from fraud, both in-store and online.
