&gt; How is this different and better for me than a credit card?<p>Klarna let you choose between invoice and credit card in their checkout (which is embedded in the retailer website, similar to other payment solutions).<p>Although they started out with invoices, I think they are better described as a payments platform these days.<p>&gt; what are their interest rates?<p>According to this document[1] on Germany, 10% - 15%. I found it through a Google search, don&#x27;t know if it holds for the US.<p>[1] <a href="https:&#x2F;&#x2F;cdn.klarna.com&#x2F;1.0&#x2F;shared&#x2F;content&#x2F;legal&#x2F;terms&#x2F;2&#x2F;en_de&#x2F;account" rel="nofollow">https:&#x2F;&#x2F;cdn.klarna.com&#x2F;1.0&#x2F;shared&#x2F;content&#x2F;legal&#x2F;terms&#x2F;2&#x2F;en_d...</a>
