Everyone will agree, my friend, that crime is everywhere and can target anyone indiscriminately. The key word is that crime may not occur because of the intention of the perpetrator, but it can happen because of the opportunity. Maybe some of us are used to being wary of crimes that can happen on the road or at home, such as robbery, theft, and even robbery. However, many of us are not aware of crimes in the digital world, even though you know, pal, that crimes can also be committed through channels such as cellphones, the internet, to your debit/credit card if you’re not careful.

There are various forms of digital crime that can occur in society, buddy. But, there are at least three digital crimes that occur most often and you should be aware of! Let’s take a cup of coffee and read it carefully~

1. Card Skimming

Card skimming is the act of stealing ATM/debit card data by illegally copying (reading or storing) information contained on magnetic strips. What is a magnetic strip, really? Okay, if you have an ATM/debit card, take a look now, on the back of your card there must always be a black line, right, pal? Well, the black width line serves to store all important information on your ATM card, such as the card number, validity period, to the customer’s name. Well, the way to copy the information on the magnetic strip is by using a card reader (card skimmer) placed in the card slot on an ATM/debit machine or even an Electronic Data Capture (EDC) machine when you shop using a debit or credit card.

In addition to these actions, the perpetrator will also try to get your ATM/debit card PIN by peeking at the button you press when transacting at an ATM machine/EDC device or it could be by placing a small camera installed in a hidden corner of the ATM machine. Well, if the perpetrator has obtained a copy of your information from the magnetic strip and your ATM/debit card PIN, then the perpetrator will create a fake card using the data that has been obtained and transact using the PIN that has also been obtained. Ihiiii… isn’t it really dangerous, pal? So… limit your personal activities on social media such as uploading birthday wishes or congratulating someone’s birth and even other important moments because criminals can track your possible ATM/debit card PIN codes based on these special dates. Remember, pal.. Social media is okay… but use it wisely and stay careful.

2. Phishing

Unlike card skimming, which uses an ATM/debit card as a channel to commit crimes, phishing perpetrators actually use internet banking channels to get data from your credit card, pal. Phishing is the act of asking (provoking) computer users to disclose confidential information by sending fake important messages, which can be in the form of emails, websites, or other electronic communications. Well, because the messages seem real and are usually followed by threats, users are often trapped by sending sensitive personal information such as user ID, password/PIN, credit card number, credit card validity period, and Card Verification Value (CVV). Keep in mind, buddy, this CVV code is usually 3 separate numbers located behind your ATM/debit or credit card. Now that you know the importance of the 3 digit number on the back of your card, be careful not to let it be known by people who have bad intentions.

3. Carding

Well, because people today really like shopping online, my friend, digital crime has also penetrated into e-commerce channels. One form of crime is carding. Carding is an online shopping activity using illegally obtained debit or credit card data. Compared to other crimes, carding is relatively easy to do because it does not require a physical card and only relies on data from the debit/credit card to be targeted. Usually, perpetrators will find and get data from debit or credit cards, either through fake marketing, fake merchants, recording sensitive data by individuals at merchants, or from lost cards. Once the person gets all of our data, starting from the card number, expiration date, validity period, CCV, card limit and other information, the perpetrator will use the data to make online shopping transactions and the financial bill will be borne by the victim. Oops… I really don’t want this, my friend, for this to happen.


Eitsss, even though you are now a little worried about the security of your financial transactions, don’t worry, buddy, because you can take some steps to protect your money from digital criminals. You can do some of the tips below.

• Never share personal information such as PIN, CVV, card number, validity period and so on with anyone via the website, SMS, internet or other channels as long as you don’t use that information to make any transactions, especially to untrustworthy persons/parties. Also make sure, pal, you always update your PIN regularly and make sure your PIN is not an easy-to-guess number such as your date of birth or front/back phone number. Remember, pal, keep your PIN, CVV, card number, and the validity period of your ATM/Debit or credit card confidential, because the fate of your financial security lies in how carefully you protect the data.

• Be careful when making transactions at ATM machines, EDC machines, or e-commerce. Make sure no one sees you pressing the button when entering your PIN code on an ATM or EDC machine, make sure your debit/credit card is not swiped/dip on a device other than EDC when shopping or swiped/dip more than 2 (two) times in one go time except due to failed transactions, and make sure you don’t download links from untrusted parties when shopping online because they have the potential to carry malware.

• Increase the security of your card through 3D Secure, namely by using a One Time Password (OTP) code that is sent via SMS to cardholder customers every time they approve financial transactions. Make sure you communicate with the issuing bank about this security feature. In addition, you can use chip technology to replace the magnetic strip that is now valid on ATM/debit cards or credit cards, which is Bank Indonesia’s policy to increase security on ATM/debit cards or credit cards.

• If there is a suspicious transaction, confirm it and report it. If there is a suspicious transaction such as an SMS or email from a suspicious party or from a transaction that you didn’t make, don’t panic and be rash to process it right away by opening the link sent or replying with your card information, but first, make sure you go to the issuing bank’s call center. about that. If you feel that you have not made a financial transaction but receive an SMS/email notification that a transaction has taken place without your knowledge, then immediately report it to the call center of the bank concerned and consult the problem so that it does not become a financial burden for you. Negotiate with the bank and immediately block the ATM/debit or credit card if the suspicious transaction originates from the card.

So friends, you don’t need to be afraid to do digital transactions and become part of a cashless society, as long as you stay alert and careful when using an ATM/debit card or credit card. There’s no difference, buddy, with your caution when carrying large amounts of cash, the only difference is the channel that the person uses when committing the crime. So, please be aware!
