Pulse Network LLC, a Houston debit unit of Discover Financial Services, said it has signed long-term renewals with two Wisconsin financial companies that use the debit network.

Park Bank, a $762 million-asset unit of Park Bancorp. Inc. of Madison, will continue to use Pulse for automated teller machine and PIN debit services, as well as for signature debit processing. Park Bank has used Pulse since 2002.

Altra Federal Credit Union in La Crosse renewed its contract to use Pulse for PIN debit transactions. The $614 million-asset credit union has been a Pulse customer since 2005.

Pulse announced the renewals Tuesday but did not provide their value or duration.
