When it comes to carding, carders use bots to check multiple credit or debit cards on merchant's websites. These people or companies, such as Bestfullzshop and Bestcvvshop2019, usually get credit card data on the dark web and test its validity with small purchases. Carders will use proven numbers to retrieve funds or buy gift cards that can be converted into goods, such as TVs, smartphones and computers. Then these goods are resold through websites that offer anonymity. Unlike account takeovers that focus on the login page, carding focuses on the checkout page using verified card information.

Carding involves hacking of cards where carders use different techniques to enumerate card numbers to get working combinations. Gift cards are used more often because they can be easily resold on the dark web. Gift cards have a low level of protection: they don't have names, zip codes or addresses associated with them. Moreover, many online stores create a separate page for gift cards, which can be easily used by carders. There are carding services, such as Cvvshophighbalance, 101dumpswithpin and Creditcarddumpsites that have stepped up their game by using bots that can mirror human behavior.
