Key security features of credit cards Everything you need to know
Credit cards are a convenient way to manage finances, but they also come with risks if not properly secured. Fortunately, modern credit cards have advanced security features to protect you from fraud and unauthorised transactions. Let’s take a look at some key credit card security features and how they help ensure your financial safety.
1. EMV chip technology
One of the most prominent security features of modern credit cards is the EMV chip. Unlike magnetic stripes, which store static information, the EMV chip creates unique transaction data every time you make a purchase. This prevents criminals from cloning your card, significantly reducing the risk of fraud.
2. Credit card tokenisation
Credit card tokenisation is another advanced security measure that protects your card details. When you make a transaction, tokenisation replaces sensitive information with a randomly generated token. This token can be used only for that specific transaction, making it nearly impossible for hackers to use the stolen information for fraudulent purchases.
3. Two-factor authentication (2FA)
Many of the best credit cards offer two-factor authentication (2FA) for online purchases. After entering your card details, you are prompted to verify the transaction with a one-time password (OTP) or biometric authentication (such as fingerprints or facial recognition). This additional step ensures that even if someone gains access to your card information, they won’t be able to complete the transaction without the second layer of verification.
4. Real-time fraud alerts
Credit card issuers now provide credit card fraud protection through real-time alerts. If a suspicious transaction occurs, you’ll receive an immediate notification via email or text message, allowing you to take swift action to block your card or dispute the charge.
5. Virtual card numbers
Some credit card issuers offer virtual card numbers for online shopping. These temporary numbers are linked to your actual credit card but can be used for a single purchase or a set time frame. Virtual card numbers help protect your real credit card number from being exposed in case of a data breach.
6. Zero-liability protection
Most credit cards today come with zero-liability protection, meaning you won’t be held responsible for unauthorised charges on your account. If your card is lost or stolen, or your information is used fraudulently, your card issuer will cover the costs, provided you report the incident promptly.
