What are credit cards?

The bank or financial institution issues the credit card. It's just a tool of payment allowing you to borrow money to buy goods or services that can be repaid later. Essentially, it works as a short-term loan, and you've got a credit limit setting out how much money you are able to borrow at any given time. Every month, a statement of your expenditures and what you owe will be mailed to you.

5 Smart tips to keep your credit cards safe

  1. Never share or reuse PINs: Set unique PINs for each card and never share them with anyone. This is important for the security of your bank account and finances. 
  2. Avoid public or unsafe transactions: Don’t use public computers or unsecured websites for online payments. Be careful with your confidential details such as CVVs, OTPs, ATM PIN along with similar details. 
  3. Don’t save card details online: Avoid storing your card info on websites or browsers to reduce fraud risk. Do note, details once shared and funds once lost are hard to recover.
  4. Use antivirus & secure networks: Install trusted antivirus software and use only secure internet connections while carrying out financial transactions. Do check the secure connection tab.
  5. Track transactions & keep support handy: Double-check credit card bills and receipts, and always carry your card issuer’s helpline number. If in doubt always speak to professionals before carrying out any digital transactions. 

Common reasons for blocking a credit card

1. Fraud or theft: When your card is lost, stolen, or used fraudulently, you can quickly stop further fraudulent transactions by blocking the card immediately.

2. Over-expenditure: Some consumers will block their cards, temporarily or permanently, with an intention to curb the tendencies of reckless spending and develop good money management.

3. Financial crisis: Blocking the credit card when one is in a financial crunch will ensure you do not incur extra debts and instead use alternative methods of making payments.
