Casey’s General Stores, Inc. today confirmed that credit card skimming devices were discovered at six of its stores in Nebraska and one store in Iowa.

Upon discovery of the first device, Casey’s launched a company-wide examination of all fuel pumps at approximately 1,900 stores across 14 states, which subsequently led to the discovery of additional devices. Casey’s immediately removed the devices and notified law enforcement authorities and credit card companies, and has instituted additional company-wide pump inspection procedures at all stores.

While it is currently undetermined if any credit card information has been compromised, Casey’s encourages customers who used credit cards (including debit and other payment cards) at fuel pumps at these Nebraska locations between October 2, 2015 and October 10, 2015, and the Iowa location between October 15, 2015 and October 21, 2015, to remain vigilant and closely monitor their financial accounts and credit reports. Customers should promptly contact their financial institutions if they see any unauthorized activity.

“We are committed to maintaining a safe and secure environment for our customers and will continue to work with federal, state and local authorities in this investigation,” said Chairman and CEO Robert J. Myers.
