It all requires funds that are not small, can be three times the household budget on weekdays. To fulfill this, some people are sometimes willing to do anything, as long as they can make money, crowded pawnshops, People's Credit Banks, Cooperatives, and loan sharks to harvest in this fasting month.

This potential is tempting for criminals to use bank services. Customers will be led to show account numbers until they make transactions through accounts to perpetrators of crime. Some cases occur because customers unconsciously provide account numbers and personal data to the perpetrators.

Then we will quickly inform you of 3 critical personal data that are confidential, only we can know. What are the important numbers? There are three secrets that we must hide; sharing with others means being prepared to take risks. The name is:

1. PIN, (Personal Identification Number), is a secret password number to enter our account.

Take care of confidentiality, remember in the head. Don't write it down even if it's photographed. Even the bank clerk doesn't know our pin.

Crime mode requires this PIN to be used by fraudsters operating at ATMs. The fraudster manipulates the ATM so that the victim fails to transact and the card is swallowed on the machine. Then came the cheating team member to direct the victim to contact the fake call center number. After being contacted, he informed him that the ATM had been blocked, then asked the victim to provide a personal identity, including the ATM PIN. This is where the disaster begins.

Should it occur if it does not need to rush to call the call center offered by the helper, but look for the original call center number from the relevant bank, which is usually printed on the ATM, or if there is no one able to search through internet access.

"If the ingested card immediately contacts the bank's call center, never give a pin to the next person who pretends to help. Maybe in panic finally [the victim wants] to give the pin,"

2. CVV (Card Verification Value) or CVC (Card Verification Code)

CVV or CVC is the last three digit number on the back of the credit card. At the place of a signature, CVV or CVC is usually located.

About CVV and CVC, Cermati.com explained. This CVV / CVC code is located in the last three digit number that is behind the credit card. CVV and CVC are the same, and the difference is the type of credit card. If the credit card with the VISA logo uses the term CVV, the credit card with the Mastercard logo uses the term CVC.

For security, there is even a suggestion to delete only the back of the number (CVV / CVC), especially the last three digits used for the safety of online transactions. Before being closed or deleted, memorize the three-digit CVV. In cases of crime, fraudsters usually target this number to be used in online purchases.

Currently, crime by utilizing this credit card CVV has been detected by the police targeting fans of the movie Avengers Endgame. Kaspersky Lab reports scammer actions to viewers who watch streaming through illegal film sites. Within minutes, scammers can pocket information on personal data from email addresses to three-digit codes (CVV) behind a credit card.

Streaming activity initially began without incident. However, a malicious threat will come after it starts; a message will appear, asking the user to create an account. Furthermore, the user will be instructed to validate the account. The account validation involves user billing information and credit card details, including CVC codes printed on the back of the card. Then the information provided by the user is in the hands of the scammers. He won, the audience was fooled because there would be no movie that had been promised. Original content aired by scammers is only part of the trailer for the film.

3. OTP (One Time Password) is a dynamic (changeable) password that is sent to the account holder's cellular telephone number.

Sent by the bank or selling site online via SMS / email. This OTP is given to requesting approval of access to our account, such as debiting an account or cutting credit. OTP can also be said as an authorization code for a transaction.

Like PIN and CCV or CVC, the existence of OTP is also very confidential. Like genitals, it must be closed, hidden, don't let anyone know because we don't know where crime can begin. Anyone has the opportunity to do, including people near us. Instead of arranging prejudices, we better protect the confidentiality of the number.
