Credit card generator: how to generate for tests?

by Team AllYourVideogames | Sep 17, 2022 | Technology |


We can define a credit card generator as a computer system that has a standard and simple operation.

In a fraction of a second, this tool creates a numerical sequence equivalent to those available on credit cards, including the security CVV code and expiration date.

A credit card generator is widely used by IT professionals.



They usually carry out tests on programs or services that have some relation to online shopping processes.

Below, we'll talk a little about what a credit card generator is and how it works, and we'll list some options for you.

How does a credit card generator work?

The sequential numbers created by the credit card generator are random.

Thus, they may or may not be linked to some consumer.

Typically, credit cards have 16 digits that are separated into three different blocks:

  • customer number;
  • Verifying digit;
  • BIN (Bank Identification Number), that is, the bank identification number.

For the card to work, it is also necessary to inform the Verifier Code (CVV) correctly, which has three algorithms, in addition to informing the expiration date of the card.


As all this data is randomly generated and unrelated, it ends up generating a non-existent bank account, that is, real transactions cannot be made with that data.

How are these tools used in IT?

IT professionals use a credit card generator to test platforms and software that may be working.



Thus, the data informed by the generator can be used in: shopping simulation, shopping websites and applications, programming tests, ecommerce development and academic purposes.

This option is also widely used by professionals to verify that the operations management of their programs is working perfectly and to identify false information.

If the transaction attempt fails, the program is working.
