With the development of technology Today we do most of our business online. we can handle it. We can have our favorite sneakers without ever leaving our house, the latest model of phone, even the food we want at the time…

While we can handle all these needs through the internet; many of us pay online and with many payment methods We have to enter our card details, even if it’s just once.he drinks. Although we enter information such as name, surname, card number, SKT when entering our card information, there is also the information on the back of our card that we don’t know what it is. CVV information we come in. Fine, but what is CVV, what does it do, why is it usually on the back of the cards? When you’re ready, activate your 3D Secures; CVV and Card Signature Section Features we will share it with you.

CVV is caused by a simple safety measure.

many of us Card Validation Value, known as CVV (card security code) was originally developed in 1995, although it was introduced in 2001.

In 1995, he was assigned to Equifax (we can say the name KKB in our country in America). Michael Stone by means of to ensure safe use When the developed application was first used by Mastercard, it was an 11 digit code and frankly it was not very useful.

The evolution of CVV ​​over the years

With the increase in the use of credit and debit cards over time, CVV developed to fix some security vulnerabilitiesLater it was introduced by American Express in 1999 as CID (Card Identification Number) and in 2001 as CVV and CVV2 on VISA cards.

CVV is an effective solution to show that the card is ours

CVV’s most basic logic, as you can see; an encryption method that shows that the card is ours that is. During a physical shopping session, the CVV password on the magnetic stripe is read by the pos when withdrawing the card from the machine or during online shopping, before 3D Secure is confirmed by CVV whether the card details are ours.

Although the names change, the logic and function never change

Brands such as VISA, Mastercard or American Express, one of the world’s leading banking services; Under the name CVV, CVV2, CID or CVC (Card Validation Code) they developed various projects with the same function. In principle, all these projects are the same. As the difference between them, used by American Express CID is on the front of the card instead of the back and the password is 4 digits We can express it as:

That part that hardly anyone drew

Whichever bank you use, on the back of your card section “authorized signature” are available. In fact, on some cards, especially under this section. “invalid if not signed” There is also a warning. Not many of us sign this field, which is just below the magnetic line.

Basically the contracts we signed and accepted when we bought these cards from banks. “If the card is used without a signature, it will be invalid” There is a ruling, but for some reason this matter is not strictly followed. I think that we, the users, do not take this problem seriously because we are not warned and sanctioned enough by the authorities.

A little warning about CVV with signature field

CVV information on some cards is located on the right side of the magnetic strip and independent you can see. While this is an exceptional situation, it is a solution offered to resolve a problem that may arise from time to time. If the card user prefers to log into the card’s authorized signature area (!), Inability to read the CVV code clearly if part or all of the signature overlaps the CVV code can occur.

Some banks process CVV information in this section, creating a small field just to the right of the magnetic strip because of this potential problem. Many banks continue to ignore this potential problem as the already authorized signature sections are left blank.

Once an era of credit cards and identity

When credit cards first came out and fraudsters sought the most opportunities credit card users show their identity while using the card, If the name on the ID and the name on the card do not match, I think everyone knows that there were times when the card was not allowed to be used, but after a certain time this application was abandoned and even today there is no trace of this application.

What about you? When shopping with a credit card, identity is requested. have you come across Do you think the current security measures are as safe as the identity application? Is your signature in the signature section of your card? Is there a reason not to sign your card despite all the warnings? You can let us know your thoughts in the comments section.
