  "summary": "EMV 3-D Secure shifts liability on a risk score or a channel response. It never binds a human to the amount and the merchant. Europe requires that. Nowhere else does.",
  "lede": "EMV 3-D Secure moves fraud liability from the merchant to the issuer when authentication succeeds. What it authenticates is a risk score or a response on a channel the issuer controls, never a human bound to this amount and this merchant. Europe requires that binding by regulation. Almost nowhere else does, and agentic checkout is about to make the difference expensive.",
