Tokyo man arrested for memorizing credit card info of over 1,300 customers to make purchases
As opposed to using data-stealing malware or other interception methods, a cashier at a mall in Kōtō, Japan was apparently able to use his eidetic memory to steal credit card details of customers as their purchases were processed at the POS terminal.
Yusuki Taniguchi would store these details in a notebook to make purchases online. The items he bought were then sold through a pawn shop and the resulting money was used to pay for his living expenses.
