On July 3, 2007, Certegy Check Services, part of FIS, announced that a worker at one of its subsidiaries stole 2.3 million consumer records containing credit card, bank account, and other personal information. This estimate was later increased to 8.5 million consumer records. The next month, a law firm filed a class-action lawsuit against CCS and parent company FIS based on the privacy breach; the firm claims that, since CCS provides check-verification services to many major U.S. stores, "consumers do not choose to use the services of these companies but rather are forced to do so".[29]
