Hello, cnv2 can't be found in mobile banking. Cvn2 code is only available on credit cards (the most obvious feature of credit cards is that the card number on the card is protruding), and it can't be searched online, because there are hidden dangers-if someone steals your bank card account number and password, your account will be unsafe, and cvn2 code can avoid this situation. The cvn2 code is the last three digits of the cardholder's signature bar behind the credit card.

There are seven digits under the magnetic stripe on the back, and the last three digits are.

The full name of CVN: Card v. ееееееееееееееее????.

This is a bank card used for indirect transactions, such as online payment. Can identify whether there is a bank card transaction. It can generally be seen in the last three digits of a series of signature columns on the back of bank cards. The UnionPay standard card organized by UnionPay is called CVN2, MasterCard is called CVC2, VISA is called CVV2, and AE American Express is called CSC2. But the principle of making it is the same.
