On July 30, 2014, Jimmy John’s learned of a possible security incident involving credit and debit card data at some of Jimmy John’s stores and franchised locations. Jimmy John’s immediately hired third party forensic experts to assist with its investigation.  This information was made public on September 24, 2014.

While the investigation is ongoing, it appears that customers’ credit and debit card data was compromised after an intruder stole log-in credentials from Jimmy John’s point-of-sale vendor and used these stolen credentials to remotely access the point-of-sale systems at some corporate and franchised locations between June 16, 2014 and September 5, 2014. The security compromise has been contained, and customers can use their credit and debit cards securely at Jimmy John’s stores.

Approximately 216 stores appear to have been affected by this event. Cards impacted by this event appear to be those swiped at the stores, and did not include those cards entered manually or online. The credit and debit card information at issue may include the card number and in some cases the cardholder’s name, verification code, and/or the card’s expiration date. Information entered online, such as customer address, e-mail, and password, remains secure. The locations and dates of exposure for each affected Jimmy John’s location are listed on

ONE AMERICAN BANK is being proactive and those customers who used their cards at Jimmy John’s during the breach time frame will be issued new cards and PIN numbers.  Cards used during this time frame will be canceled and new cards and PINS reissued in an attempt to protect our customers. 

If you have any questions regarding your account, you may call us at 605-361-1010.

Pierre, SD: Attorney General Marty Jackley is warning South Dakota consumers to be cautious of robocalls targeting cell phone users with a scam that implies that their debit cards have been comprised. The automated phone message prompts the consumer to press a number one to unlock the card. Once the number one is pressed the consumer is connected to a live person who the requests the debit card number, current address and confirmation of recent transactions. The scam artist then asks for a PIN number in order to reset the card. Consumers should refrain from giving out any personal information and to hang up without pressing any numbers.

If you believe you are a victim of this scam or need any additional information contact the South Dakota Consumer Protection Division at 1-800-300-1986 or Anyone who has given out personal financial information should contact their financial institution immediately.
