5 Tips for Credit Card Security

Basically, such crimes run smoothly thanks to the data they steal from customers. Therefore, these sensitive data must not be known to others. It would be nice if you are careful every time you use it. You can start with the simplest step, which is to treat it like cash. In addition, there are still several ways to improve credit card security. Want to know what are the ways? Check it out, huh.


Note the Transaction System on your Credit Card

Credit Card

There are two types of transaction systems attached to credit cards that are commonly used in Indonesia, namely magnetic swipe systems and chip systems. Unfortunately, both of these systems can be hacked. The reason is that this system utilizes the credit card holder’s signature as access to the entry while the signature is vulnerable to being falsified. If so, anticipate that is by always watching when you transact with this credit card. Make sure that the cashier only swipes once. If he rubs more than once (double swipe), it’s possible your data can be stolen.

The second credit card system is the chip system. This system requires users to enter their PIN every time they make a transaction. You could say this credit card is safer because the PIN is confidential and only the owner knows. To be sure, whatever type of system is used on your credit card, make sure that all of your transaction receipts are kept as proof later.


Pay attention to your Credit Card Number and CVV

Pay attention to your Credit Card Number and CVV

CVV stands for cardholder verification whose form is in the form of three or even four-digit secret codes that are pinned behind your credit card. For example, the Master Card or Visa credit card has a three-digit secret code while the American Express Card has four digits.

CVV numbers are usually used in online transactions for security purposes. However, that is not entirely true. Because the CVV number has something to do with your credit card number in front. This means to protect your credit card, not only with CVV numbers, but also with a credit card number of 16 digits.

What you need to remember, do not just share the number of your swipe card to another person. Even if you give the number to transact online , you should note on any website the data is circulating. For example hotel reservations, e- commerce and others.

For administrative purposes, often certain agencies require photocopies of ID cards or other documents. Except for a credit card, don’t even copy it. Why? This is for security. Even if it’s just a photocopy, know that credit cards can be misused by other people. In addition, the bank never requires a photocopy of a credit card every time the transaction.


Notification of Transactions via Mobile

One of the conveniences offered by credit cards is in the form of notifications through your cellphone. You must ensure that the recipient’s cellphone number is only known by the credit card issuing bank.

If you don’t feel like doing the transaction, you can call the contact center so that the transaction can be canceled immediately.
