Jimmy John’s is warning its customers of a "possible security incident involving credit and debit card data."
According to a letter posted on the company's web site, the problem was detected at approximately 216 Jimmy John's corporate and franchised stores between June 16 and Sept. 5 of this year.
Company officials say it appears that customers' credit and debit card data was compromised after someone stole log-in credentials from a point-of-sale vendor, and used the information to remotely access the systems at the individual stores.
The security issue has been contained and the company says customers can continue using their credit and debit cards securely at Jimmy John’s stores. Third party forensic experts have been brought in to assist with the investigation.
The Champaign, Illinois-based sandwich chain says cards affected by the breach include those swiped on certain dates at these individual stores.
