A “skimmer device” was discovered by a service technician at Bank of America’s Automated Teller Machine (ATM) at the South Shore Center on Monday night, the Alameda police confirmed through a statement.

The said device is a notorious way to gather pin codes and card numbers that can result in bank account fraud incidents, KRON4 reported.

The ATM machine’s mirror and camera bar replica were found by the technician at a pinhole camera.

According to the police, it seems like Bank of America had been targeted by criminals, as well as the California Employment Development Department (EDD) debit cards users.

It added that it looks into the possibility that the skimmer device was put up to four weeks ago.

The Alameda police and the Bank of America are working with each other to have the suspects identified.

ATM users are told to take precautions when using the machine. When entering the PIN, people are told to use their hands to cover the PIN pad. In-person processes are also considered a safer way to access the bank.
