The security code (CVV2 or verification value) is used to confirm cardholder authenticity when transactions are carried out by phone or online. It’s made up of the last 3 or 4 numbers printed on the signature panel on the back of the card, or in a white box to the right of the signature panel, or on the front of the card just above the credit card number.
The code is unique to each card and does not appear on the magnetic stripe, which means fraudsters can't get hold of this data because it can only be seen by someone who is actually in possession of the card.
This feature will help you validate the cardholder's authenticity when they are not present, in order to prevent fraud-related problems.
To help prevent fraud on card-not-present transactions, Visa now requires that the Card Verification Value 2 (CVV2) be captured for all telephone and online transactions.
To comply with this requirement, we are making it mandatory to enter the CVV2 on all telephone and online transactions.

Authorization doesn't validate the transaction, it simply confirms that funds are available and the card is active at the time of the transaction. It doesn't guarantee that the person holding the card is the cardholder.
During a transaction, sensitive information such as your customers' credit card numbers is transmitted, processed and sometimes saved for a few moments. To make sure that sensitive data is protected during every step of the transaction process, PCI DSS require the adoption of certain security measures. It's therefore important that you don't store any of this type of information, either on your computer or on paper.
Based on EMV chip card technology, the contactless payment method offers increased security and protection against fraud. Transactions are as secure as if the card had been inserted in the chip reader.
