This article will guide you through recognising and reporting fraudulent transactions.

What is Credit Card Fraud?

Credit Card fraud involves the unauthorised use of a Credit Card to make purchases or withdraw funds. This type of fraud can occur in various ways, such as through lost or stolen cards, data breaches or card skimming. Recognising the signs of Credit Card fraud and understanding how to avoid Credit Card fraud is crucial in protecting your finances.

Common Types of Credit Card Fraud

The following are commonly occurring Credit Card frauds:

  • Card-Not-Present Fraud: This type of fraud occurs when your card details are stolen and used to make purchases online or over the phone. Since the physical card isn’t needed, it’s easier for fraudsters to exploit.

  • Card Skimming: Skimming devices are often placed on ATMs or point-of-sale terminals. These devices capture your card’s magnetic strip data, which is then used to clone your card.

  • Phishing: Fraudsters send fake emails or texts posing as legitimate companies to trick you into revealing your card information. These messages often contain links to fake websites that look like real ones.

  • Lost or Stolen Cards: If your card is lost or stolen, it can be used by anyone who finds it, especially if they also gain access to your PIN.

Signs of Credit Card Fraud 

These signs may indicate a Credit Card fraud:

  • Unrecognised Transactions: Regularly check your account statements for any transactions you do not recognise.

  • Unexpected OTPs: Receiving one-time passwords (OTPs) for transactions you did not initiate may indicate that someone is trying to use your card details without authorisation.

  • Unauthorised Account Changes: If you suddenly stop receiving statements or notice changes to your account that you didn’t make, there could be a possibility of fraud.

Immediate Steps to Take When You Notice Fraudulent Activity
