BROOKFIELD, Wis. – In credit union land, core processing giant Fiserv is not normally thought of as an Internet banking vendor, but the company says it's pushing that functionality hard on the bank and thrift side. Fiserv said sales of its consumer and business Internet banking platforms – Premierecom and Premierecorp – have averaged 20 and 25 per month, respectively, over the past couple years. There now are about 1,200 financial institutions using Premierecom, the consumer solution, and about 550 licensing the Premierecorp business banking software, the company said. “This growth is all organic, rather than the product of acquisition,” said Rodney Poskochil, president of the Fiserv Bank Systems & eProducts Group. “More than half of the financial institutions most recently added to our client list have elected to migrate to our solution from someone else's product. For the balance, this was a first-time offering of Internet banking.”
