A device that steals personal information such as debit card numbers and personal identification numbers while attached to an ATM was found Saturday at Rogue Credit Union's Ashland branch.

A customer found the device, called an ATM skimmer, at about 8:30 a.m., according to Rogue Credit Union marketing manager Kelsey Esqueda.

"We're always asking our members to be vigilant using ATMs," Esqueda said. "(They) noticed a device that didn't look typical."

The device, which was placed at about midnight was "caught quickly," according to a Rogue Credit Union Facebook post, and affected 19 customers. The financial institution has reached out to all of them. No money has been reported stolen.

"We haven't had any fraudulent activity so far," Esqueda said.

Who put the skimmer on the ATM remains under investigation, according to Ashland police Officer Matt Carpenter.

The devices are often placed over or inside the slot where customers insert their card. Sometimes they will be paired with a camera. 

"Oftentimes there are a couple fake components that are put on the ATM," Carpenter said.

ATM users can spot skimmers if they know what to look for. Oftentimes, those components will not match the ATM's facade. The card slot may also appear to be loosened.

Sometimes, the devices can be difficult to detect, however. Officials recommended ATM users wiggle their cards to see if the slot is loose. If it is, stay away.

"That is definitely a telltale sign," Carpenter said.

Similar devices were located on ATMs in Central Point and Medford in 2015.
