Cincinnati Bell Inc is selling much of its Cincinnati Bell Information Systems unit in pieces, and the latest bit to go is the banking unit, which provides image and document management systems to the banking and financial services marketplace. The buyer for the unit, whose products are designed to enable financial institutions to produce easy-to-read cheque account statements for customers, simplify the cheque verification process and to store and retrieve imaged information, is FIserv Inc, of Brookfield, Wisconsin, a suburb of Milwaukee. The banking unit is based in Maitland, Florida and FIserv says it intends to retain the 38 employees of the group. Terms were not disclosed.
