Have you used the ATM at U.S. Bank at 2040 Silvernail Road? You might want to keep an eye on all your bank statements.

A person who was working on the machine Saturday afternoon reported finding a "skimming" device and a camera, according to the Waukesha Police Department's call log. The incident is being investigated by the Waukesha Police Department. Police have not yet identified any victims and it is unknown if and how much money could be stolen through the reader, according to Sgt. Jerry Habanek.

U.S. Bank is contacting customers who may have had their credit and debit card accounts compromised, Habanek said. "They know what cards were swiped during the period that the skimmmer was on the ATM machine," Habanek said.

From the Waukesha Police Department: Police responded and discovered a skimmer insert that had been placed over the card reader. Also located was a blue bar that sat on top of the machine that contained a pinhole camera. This camera recorded pin numbers that were punched into the keypad.

A technician from Diebold explained that the way he could tell that the ATM machine had been compromised was that the card reader did not light up when a card was inserted. He also noted that the blue bar containing the pinhole camera was colored a slightly lighter blue than the screen.

The Waukesha Police Department needs your help in identifying the suspect pictured. This photo was taken by a near by surveillance camera. Anyone who has information regarding the person in this photo please contact Detective Tom Casey of the Waukesha Police Department at 262-524-3924.

How to Avoid ATM Scams It's extremely difficult to find skimmers. The devices can easily fool an unsuspecting person who is using the machine. The skimmers store the credit card information and coupled with the hidden camera, can be a serious breach in debit and credit card security. Criminals using ATM skimming devices have made off with about $1 billion annually of other people's money, according to the Wisconsin Better Business Bureau.
