Agentic payments design debate: should an AI shopping agent insert its own virtual card?
Danhightower · x · 2026-11-05
Author scottew reports that when using the AI assistant Muse to buy from Best Buy, Muse and Stripe Link replaced his Amex with their own virtual Visa card, creating a confusing payment experience; his article calls for simpler agentic payments design.
Danhightower's commentary applies a golden rule: don't build middle layers that needn't exist — the intermediate virtual card isn't required for the user to buy anything, and may exist mainly so intermediaries can take a cut. The case highlights the core design tension of who holds the user's payment credentials in agent-mediated purchases.
