Credit card cvc refers to the credit card security code, which is the check code of the credit card and recorded in the magnetic stripe of the credit card. You need to verify this code when swiping the card. What needs to be verified when conducting telephone transactions or online transactions is the cvc2 code, which is generally recorded in the signature column on the back of the credit card, and is the last three digits.
1. The CVC of a credit card means the last three yards. The last three codes CVC(CardVerificationCode) are additional codes printed on the back of the credit card, also known as CVV. (CardVerificationValue), that is, the credit card verification value. The display position is on the back of the credit card, and the top of the signature is displayed in italics. The first four digits are, and the last three digits are the verification code, that is, the last three digits.
2. Note that this verification code does not refer to the password of the credit card. Just enter the bank and the last three digits, as well as the validity period of the credit card. There is no password at all.
3. The information you need to provide when buying a ticket with a credit card is: the validity period of the credit card, the "last three" verification code and the cardholder's ID number.
4. The use of credit cards can be divided into "on-card transactions" and "off-line transactions". In the former, the cardholder swipes the card at POS terminals such as shopping malls and supermarkets, signs the authorization, and then completes the transaction. Offline transactions are common when cardholders book hotels, air tickets or pay online. The merchant also provides the credit card account number and the last three codes through the POS system to complete the transaction.
The risk of the last three yards:
1. At present, many domestic airlines and booking websites do not need to enter a password for the credit card payment business, and they can successfully pay by providing the website with information such as the expiration date and verification code, so the credit card and other related information is particularly important, and this information is easy to be obtained by people they know.
2. The last three codes are very important in offline transactions, which brings convenience to cardholders and merchants. Cooperate with qualified merchants, and the merchants will freeze some funds before the cardholders spend. After the cardholder signs the money, the merchant can formally deduct this part of the funds, and try to avoid the phenomenon of running the bill.
3. The last three digits are the last three digits on the back of a series of cards, which are generated by the coding rules and encryption algorithm of the issuing bank. In the payment process, if the merchant provides the last three codes to the bank, the bank will obtain the authorization of the cardholder to the merchant by default, thus allowing the transaction.
