Dollar Bank, the nation's largest independent mutual bank, has tapped Fiserv Inc., a provider of financial services technology solutions, to update its digital banking and payment capabilities with a focus on the customer experience.

One of the first financial institutions in the U.S. to offer online banking, Dollar Bank will integrate Architect from Fiserv, providing the FI a single platform for retail and business banking across online, mobile and tablet devices, a press release said.

Additionally Dollar Bank will add electronic payment solutions that include CheckFree RXP for electronic bill presentment and payment, Turnkey Service for Zelle P2P payments, and TransferNow for account-to-account transfers.

Architect is compatible with the bank's proprietary core processing platform, and can support its real-time operations approach, the release said.

"We are a real-time bank posting transactions as they occur instead of in one batch," said Joseph Toth, Dollar Bank executive vice president and chief operating officer. "Real-time is fundamental to how we operate, so we have to be sure any surround technology will fit into that environment."

"For the majority of people, their daily banking experience is a digital experience," said Kevin Schultz, president of digital banking at Fiserv. "Delivering more robust digital banking and payments capabilities aligned with how people prefer to bank will enable Dollar Bank to continue to build lasting connections with their customers."
