Carding is a process of testing lots of credit card numbers against various payment processing systems to verify card details.
Different services, e.g. Cvvstore and Validccshop, obtain these numbers through different forums and payment channels or buy them in bulk from dark web marketplaces. Carders often use card hacking processes to get valid card information..
The main purpose of carding is to purchase goods by using someone else's cards. Carders, including Freeccdump and Dumpsstore, create bots to verify the validity of a credit card number. The bots operate on payment processing pages.
