Everyone is probably used to using credit cards for making purchases, right? And when it comes to online shopping or using various online services, we need to enter the number on the front of our credit card as well as the three digits on the back, correct? Did you know that those three digits on the back of our credit card are very important for online transactions? Let's take a look at the significance of the number on the back of the card.

The number on the back of the card is the CVV, which stands for Card Verification Value Code.

          So what is the role of the CVV? During each online transaction, we need to enter it as a verification code or to confirm our identity when purchasing goods or services, or completing online transactions at the final step. This three-digit number must not be shared with anyone under any circumstances. If someone obtains these three digits, they can use them to make online purchases by filling in the necessary details, and the last step will be entering the CVV. Even if we have a credit card, it can be easily misused, leading to complications and debt without us realizing it. Therefore, we should keep our credit card information as confidential as possible, including details from the front to the back of the card, especially the credit card number and the CVV. Once we receive a credit card, it is advisable to note the CVV elsewhere or memorize it, and to cover the number on the back of the card with a black marker.

OTP: Another Step for Security

          If you frequently engage in online transactions, you are probably familiar with receiving an SMS with an OTP, which stands for One Time Password. This is a code used only once to access the system, sent to you via SMS to the phone number you provided. The OTP is beneficial in that you do not have to remember a password and helps maintain security by preventing others from using your code.

          Take a moment to check your credit card to see if the CVV is clearly visible. If you want a new credit card, you can compare credit cards yourself on the masii website just click here.
