KLAR vs MRNA Comparison

Klarna is the largest pure-play in the buy now, pay later space. The company operates a two-sided network with a payment method at its core, but it is ultimately a lender. Merchants sign up with Klarna to increase turnover in their stores. Primarily, Klarna can provide merchants with higher conversion rates and average order values relative to other payment methods. Some merchants enter a symbiotic relationship with Klarna, advertising its brand on the product page to drive conversion and to benefit from Klarna's brand value in the merchant's sales funnel. Customers use Klarna for its ease of use, quick access to credit, zero-interest financing, and lower reminder fees.
