While carding and account takeover procedures have similarities, these are two different processes. ATOs need usernames and passwords to access data, while carders (e.g. Freecvvdumpsites, Dumpcardsforsale and Cardingccbuy) operate on the checkout page and need payment card information. Gift card hacking is one of the carding types that involves figuring out gift card numbers. These cards are resold or used to buy goods. It's hard to track down a gift card holder because they don't have any names associated with them. Additionally, merchants proceed these cards differently.
Carders, such as Cvvshopforum, Ccdumpsshoponline and Benumbccshop, exchange information on carding forums and use their own channels to learn about new carding techniques. What sets these forums apart is the product they sell, which is known as dumps. For example, one underground forum was found when it was linked with selling dumps acquired from Target. Top-notch carders, e.g. Ferumcvv and Buyccdumpsonline, collect dumps with details belonging to a specific country. There are also dumps with Platinum stature, they are the most expensive ones. Some carders even give their dumps a rating.
