Self-Help Credit Union is suing Fiserv for allegedly misleading clients about its security measures, claiming it falsely represented the use of two-factor authentication. The lawsuit highlights a discrepancy between what Fiserv billed for and what it actually provided. This case adds to a series of legal challenges facing the payments processor.

Investors have filed a lawsuit against payments processor Fiserv, claiming the company misled them by forcing merchants to migrate to its Clover point-of-sale system while falsely inflating growth numbers. The complaint alleges that this migration concealed a slowdown in new merchant acquisitions and that Fiserv's executives made misleading statements about Clover's performance. The lawsuit is seeking class action status for investors who purchased Fiserv stock during a specific time frame.
