Agentic payments

• In September 2026 W3C and GS1 co-host a Workshop on E-commerce for Humans and AI Agents . There will undoubtedly be discussion on the findings from that meeting at the WPSIG meeting early in the week at TPAC, and we should leave time for follow-on discussion at the WPWG meeting.

  • Should we try to organize a joint discussion with the privacy folks?
