The devices were found at the 7-Eleven at 7413 W. Irlo Bronson Memorial Highway, the Shell gas station at 5355 E. Irlo Bronson Memorial Highway and the Circle K at 3820 Canoe Creek Road, deputies said.

The Sheriff's Office said users should inspect card readers to see if they appear different from other pumps. Also, deputies urged customers to avoid using PIN numbers at gas pumps.

Anyone with information about the pair is asked to contact the Osceola County Sheriff's Office or Crimeline at 800-423-TIPS.
