1. Will the same payment provider use different fraud system models? , if they are all fixed, what characteristics will each company’s fraud system model have so that we can better bypass it? If it is not fixed, does the merchant decide which fraud model the payment provider matches?


2. Can a credit card be used for one purchase on the website? How to better utilize the maximum value of the card? Do you need to find different websites, different payment providers, and different fraud systems for carding?

3. Regarding the use of cc detection tools:

3-1: There are two types of viald detection: one is small-amount payment, and the other is pre-authorized 0 USD payment. Should the damage caused by these two schemes to the card be better? Is the second one better? Will micropayments provide cardholders with the ability to discover that we are carding?

3-2: Will it be better to manually detect the validity of card requirements in different countries and test websites in that country?

3-3: AVS detection is to detect whether the card address and card number match? Or check whether this card has AVS enabled? If you just check whether it is turned on, I think the check is meaningless. I can only hope that the card provider captures the correct information.

3-3: Use the checking tool to check whether the balance is really real? (I don’t want to call the bank and ask what the balance is, security is harder to grasp)


4. How do you usually use tools to find the target 2D website?

5. The NoVBV card can be swiped by websites with 3D verification, but because the website has enabled 3D verification, it will still be forced to skip OTP verification, or will the website skip OTP verification, but the card will ignore this verification?


6. Do you think IP and user-agent are important when picking up a card in cc shop? Wouldn't it be better to completely imitate the cardholder's browser information? But I saw that there are relatively few cards with user-agent. With IP information, you can better find nearby IPs.

thanks so much for your reply
 
Looking forward to an answer from a carder with rich experience, thank you very much @BadB
