Final answer:
The card pin is a unique numerical code used to verify the identity of the cardholder and authenticate transactions.
It is created during the card activation or registration process and must be kept confidential.
Step-by-step explanation:
The card pin is created to provide security and protect the user's information.
It is a unique numerical code that is used to verify the identity of the cardholder and authenticate transactions.
The process of creating a card pin typically involves the following steps:
- The user selects a pin code, usually a combination of numbers, at the time of card activation or registration.
- The pin code is securely stored in the card's memory or a database associated with the card.
- When the user enters the pin code during a transaction, it is compared with the stored pin code to authenticate the user and authorize the transaction.
It's important to keep the card pin confidential and not share it with anyone to prevent unauthorized access to the card and its associated accounts.
