Fiserv has extended its relationship with Bank of America (BAC).

The financial technology provider said Tuesday that the nation's second-biggest bank by assets has renewed its subscription to Fiserv's electronic bill pay and presentment service through 2022.

Bank of America will keep using Fiserv's CheckFree RXP platform as part of the agreement.

"We are honored to continue our partnership as the next generation of payment innovation and consumer experience moves to the forefront of banking," Jeff Yabuki, Fiserv's chief executive, said in a press release.

Financial terms of the deal were not disclosed.
