It is much easier to get hold of the necessary information contained on plastic than bank card users think about it. Often fraud occurs due to the fault of the bank customers themselves due to negligence and inattention. Scammers can easily spy the secret code from behind the shoulder when paying by the owner of a bank card in a store, withdrawing cash from an ATM, etc. In addition, there is a conspiracy of attackers with sellers who can provide fraudsters with information from the payment cards of buyers. Sometimes scammers negotiate with bank employees. They tell them at what address the credit card ordered by mail will arrive, which the thieves intercept and withdraw cash. A common method is to infect mobile devices with Trojans that steal data when a bank card holder pays online.
