Credit card stuffing, card verification or just carding is an action carders perform to authorize payment cards. Even though carding is done by bots, the process is controlled by a person or a website (e.g. Cvvdumps2018, Cvv2store andFreeliveccdumps). The main objective of carding is to find which cards are active. For online stores, carding leads to chargebacks – the merchant will have to return the money and revise the transaction. Serious carders such as Cliniqueccdumps and Bestplacetobuyccdumps can execute thousands of tests in minutes. This leads to poor merchant history.
