(CNN) A store cashier in Tokyo been arrested on allegations of stealing the credit card information of 1,300 customers using just one tool -- his memory.
The part-time worker was arrested Thursday for stealing credit card details to buy $2,600 (270,000 Japanese yen) worth of bags from online shopping sites last March, according to the Tokyo Metropolitan Police.
A police source familiar with the investigation told CNN that the man, who worked at a shopping mall in Koto ward, had allegedly memorized customers' credit card information while processing their orders -- then recalled the credit card details later to shop online.
The suspect has a photographic memory and police have found a notebook with card details listed in it, said the source working on the investigation.
Japanese investigators can hold any arrested suspect for up to 20 days before they are charged.
