This is a nifty little device: a credit card with an onboard one-time password generator. The idea is that the user enters his PIN every time he makes an online purchase, and enters the one-time code on the screen into the webform. The article doesn’t say if the code is time-based or just sequence-based, but in either case the credit card company will be able to verify it remotely.
The idea is that this cuts down on card-not-present credit card fraud.
The efficacy of this countermeasure depends a lot on how much these new credit cards cost versus the amount of this type of fraud that happens, but in general it seems like a really good idea. Certainly better than that three-digit code printed on the back of cards these days.
The credit card generator generates credit card numbers in a random manner, which guarantees that the generation is valid, based on a numerical pattern and digit verification. These fake cards obtained by a credit card generator are not used to make any purchase, because although they are valid the numbers are fictitious, so they are used only by those people who need to generate a transaction, usually online and They should check to have a credit card, but do not count on it.

A credit card is a form of financing, so the owner assumes the obligation to pay the amount he or she had, in addition to the interest generated by its use, including bank fees and expenses previously agreed upon.
