Fla. Stat. § 817.685

In any action brought under this part, the authentication or identification of the business records of a credit card issuer is evidence sufficient to support a finding that the record in question is what its proponent claims, if the records are supported by the testimony of a designated representative of the credit card issuer. Such designated representative who has received the business records from the custodian of such records shall be considered a qualified witness within the meaning of s. 90.803(6)(a).
