Payment cards

A growing number of companies like Klarna, Sezzle and Circle let consumers split large purchases into smaller transactions paid over time. But they say they need to offer more than one product to set themselves apart and build customer loyalty.

The private-label card issuer has expanded into co-branded Mastercard accounts with several retailers, which have higher payment rates and fewer delinquencies than cards exclusive to partnering store chains.

In a surprise move, the Supreme Court will decide whether Amex may bar merchants from steering customers to less expensive card networks. The card issuer will have to prove the consumer gain from its practices outweighs the merchant pain.
