Affirm (NASDAQ: AFRM) is expanding its long-standing partnership with Stripe to soon support Shared Payment Tokens (SPT), which let AI agents initiate purchases using a shopper's permission and preferred payment method without exposing sensitive credentials.

The collaboration will soon bring Affirm's pay-over-time options to checkout in AI-driven commerce experiences, so shoppers can see the total cost upfront and select a clear repayment plan even when an AI assistant is helping them browse and buy. Meanwhile, merchants will be able to accept those payments on the backend through Stripe.
