Hello, Im new to this being on the dark web but have been truly interested in credit cards and how to use them online easily and how to make physical cards. I have purchased a MSR-600X reader/writer and am struggling trying to use it because I dont really understand what things like the service code is or how to get it if I jiust habve the Card Number, CVV and EXP date. If anyone is willing to help me please do so, I would gladly listen to any advice given
