The CVV code is on the signature line on the back of the card. There are seven digits on the back of the card. The first four digits are the last four digits of the card number, and the last three digits are the security code CVV2. The security code is entered when making phone or online payments to verify the identity.
1. Credit card CVV code
The CVV code of a bank card is a 3-digit or 4-digit number generated by the card number, validity period and service restriction code. It is generally written on the magnetic stripe of the card. The user-defined data area is invisible to the naked eye. The last three digits we usually see on the back of credit cards are actually CVV2, not the CVV code.
2. What is Cvv
1. The full name of Cvv is Card VerificationValue. Simply put, it is a string of additional codes printed on the back of the credit card, usually written on the 2 of the card’s magnetic stripe. The track user-defined data area usually consists of 3 or 4 digits.
2. What we call cvv now not only refers to the additional code on the back of the credit card, but also refers to the domestic use of various channel models to use cvv codes to commit fraud. A way to make money by yourself.
3. CVV industry chain and its main markets
1. Different from the complicated domestic payment methods, there are only three main payment methods on foreign online shopping websites, namely PayPal, credit card and numerous third-party payment methods. Among them, the most popular payment method is credit card.
2. One of the most important reasons is that foreign credit card payment is very convenient, and when using a credit card to pay, you don’t even need a password, as long as you have CVV information, including the card number. Validity period, three-digit CVV code, with this information, foreign credit cards can complete the payment. At the same time, these are also the basic conditions for the CVV industry project.
3. The profit method of this type of industry can be summarized in one sentence by purchasing CVV materials and then stealing credit cards to make profits.
4. CVV industry chain model
We divide it into two periods, the early stage and the late stage. In the early days, fraudsters usually used channels to directly create PayPal accounts in batches. After stealing bank cards in batches, they transferred them to personal PayPal accounts and then withdrew money to bank cards. In the later period, mainly due to the upgrade of PayPal's risk control and serious account freezes, its industrial chain model evolved into: buying materials--online shopping--receiving goods--reselling. This model has not continued to this day. Make another change.
