3 Most Useful Features of a Credit Card Number

The credit card number is a series of numbers embossed on the surface of the card, located above the cardholder's personal information. This series of numbers usually ranges from 16 to 19 digits, and is created according to a certain rule.

Here are three useful features of credit cards:

Transfer money to credit card

Customers can transfer money to credit cards via credit card numbers. This feature works on ATM systems, Internet Banking and Mobile Banking.

Check limit

To check your credit card limit by calling the bank, you need to provide the first 6 and last 4 digits of your credit card. Each credit card has a different limit, depending on the cardholder's ability to pay off the debt.

Use payment instead of pin code

Credit cards can pay for most consumer bills, shopping such as food bills, movie bills, electricity bills, water bills... Then, the cardholder can completely use the credit card number and CVV/CVC number (3 digits on the back of the credit card) to complete the payment process.

Thus, the credit card number is as important as the account number. Therefore, users need to keep this number confidential. If the information is accidentally revealed, the cardholder may lose money in the account or get involved in fraudulent transactions related to the law.

Notes when using credit card numbers

In addition to the embossed number on the front, the back of each credit card also has a CVV/CVC (Card Security Code) security code. If this security code is revealed, the cardholder is at risk of having their information stolen and facing financial risks.

Therefore, to ensure safety, customers should cover the CVV/CVC code; sign directly on the back of the card; register for SMS Banking service; do not log in account information on unreliable websites; absolutely do not let others borrow or use the card.

When paying at stores, supermarkets... customers only give their credit card to the staff and receive the card back immediately after paying. At the same time, it is necessary to carefully observe the staff's payment process to ensure there are no errors.
