What is the primary function of a card number generator?

The primary function of a card number generator is to produce a list of valid account numbers. This process typically involves generating conforming sequences that adhere to the specific rules and protocols established by payment networks and financial institutions. These algorithms ensure that the generated numbers are valid in terms of their structure and checksum validation, which is crucial for the integrity and functioning of electronic transactions.

In practical applications, card number generators may be used for testing purposes by merchants and developers, enabling them to simulate payment processes without the need for real card data, thereby ensuring compliance and security during the development phase of payment processing systems. This function ultimately supports the secure and efficient handling of electronic transactions in various contexts.
