The following are some reasons for which an action to block credit card access can be initiated:
Failure to Clear Dues: Regularly missing your payment deadlines or failing to pay the minimum amount can lead to an automatic restriction on your card usage.
Irregular Spending Patterns: If your bank detects transactions that do not match your usual behavior, they may freeze the account to investigate potential fraud.
Missing or Misplaced Card: When you report a card as lost, the issuer will immediately block credit card functions to ensure no one else can use it.
Over-Limit Spending: Attempting to spend beyond your assigned credit boundary can trigger a temporary block as a safeguard against over-leveraging.
While knowing how to perform a credit card block online is useful for emergencies, prevention is the best defense against fraud:
Shield Your Information: Always cover the keypad when entering your PIN and keep your card visible during physical transactions.
Confidentiality First: Never share your CVV, OTP, or card information with anyone, even if they claim to be bank officials. A bank or NBC never asks for sensitive or personal information over a call.
Identify Phishing Attempts: Be skeptical of unsolicited calls or emails asking for login credentials or personal financial data.
Memorise Your PIN: Never write your PIN down; memorising it prevents theft from physical documents
Audit Your Activity: Make it a habit to review your statements weekly to spot and report any small, unauthorised test transactions.
Activate Instant Notifications: Ensure your SMS and email alerts are turned on so you are notified the second a transaction occurs.
Verify Digital Security: Only shop on websites with ‘https’ in the URL and use unique, strong passwords for your banking portals.
Minimise Digital Footprints: Avoid saving your credit card information on retail websites or browsers to reduce risk in the event of a data breach.
Emergency Readiness: Save your credit card’s official customer care number in your phone contacts so you can report a lost or stolen card immediately.
Secure Physical Transactions: Keep your card in sight during payments, check receipts to ensure the amount is correct, and avoid carrying all your cards at once to minimise loss.
