Question ATM

[Jokem]

Hello I have some questions about using dumps on ATM. I am looking to buy from Brian's club and I see that there is dumps with pin. Do they work and how are they working? Do they come with Track 1 and Track 2 or just Track 2. If they come with Track 2 do I need to generate Track 1 for cloning and do I need a random name for Track 1 or they are coming with names. Thank you in advance!
