Even though Jimmy John’s says credit card data was stolen from 216 stores nationwide, the Hyattsville location, and most local locations were not affected.

From the Washington Post:

The Champaign, Illinois-based chain said in a news release that stores in 37 states across the United States were affected. It did not say how many customers are affected.

Jimmy John’s believes someone stole log-in credentials and remotely installed malware on machines used to swipe credit cards. Some customers’ credit card numbers, expiration dates, verification codes and names were stolen between June 16 and Sept. 15, the company said.
