Florida's largest credit union, the $9.8 billion Suncoast Credit Union in Tampa, is denying claims that it cost a checking vendor more than $2 million for allegedly breaching a contract agreement.

According to a lawsuit filed earlier this month in federal court, the Econ-O-Check Corp. in Stockbridge, Ga., signed an agreement last year with Suncoast CU under which the credit union agreed to establish and promote ECC's secure checking program at its 68 branches beginning in April 2018.
