Adoption of the new technology will allow users to receive electronic bills from nearly 500 companies including utility, mobile phone and credit card firms, and access to faster payment capabilities.

CheckFree RXP uses the Fiserv biller network and the data fed e-bills to provide consumers with access to bill details through the bank’s billpay service.

It also automates the bill payment process and eliminating the need to visit multiple websites to see and pay bills.

The electronic bill payment is also equipped with "Payment Assistant" capability, which allows the bank’s customers to receive, view and pay all their bills at one place according to their convenience.

In order to customize the bill payment user interface, the lender will also implement the CheckFree Builder web services API, which leverages the integration of CheckFree RXP into the bank’s online and mobile banking services.
