Tampa-based fast food chain Checkers Drive-In Restaurants Inc. announced a data breach Wednesday that affected an unknown number of customers' payment card information. According to the company, malware on some payment card readers at just over 100 Checkers and Rally's locations siphoned information including cardholder names, payment card numbers, card expiration dates and card verification codes.

About 15 locations were in Florida, 10 of which were in Tampa Bay. The breach affected about 15 percent of the chain's stores. Checkers did not disclose over what period of time the breach took place.

The chain recommends that those who may have been affected check their billing statements, order a credit report and report any incidents to the Federal Trade Commission.
