For the use of CC today it is not as easy as they paint it to have a good carding you have to take into account several factors
I worked 20 years with fraud, cloning of cards as well
and I can tell you that it is not so easy anymore, for example
a card can have a million but if it has a lock you will never be able to use it, there are many factors
it can have an OTP code, it can have a vbv or MSC
but there are boots that bypass all that security at the time of purchase
