Synthesis
The compared protocols sit between announcement and live pilot. Visa's Trusted Agent Protocol reached a live European pilot announced 2026-07-02 — roughly thirty financial institutions and real purchases at independent merchants, corroborated by independent Spanish financial press, though the independent account attributes part of the mechanism to Visa Payment Passkeys rather than TAP by name. Alipay+'s Agentic Mobile Protocol was released and open-sourced on 2026-04-27/28 — generally available as a specification, with wallet-network implementation still early. Visa Intelligent Commerce Connect was unveiled 2026-04-08 as a select-partner pilot (Aldar, AWS, Highnote, Payabli and others); a June GA target was reported, with no GA confirmation found as of mid-July 2026. Mastercard's Agent Pay has progressed from first completed transactions (Australia with CommBank and Westpac, January 2026; Europe's first live-production end-to-end transaction with Worldline and ING, June 2026; France's first production transaction with Worldline and Crédit Agricole, 2026-06-25) to the introduction of Agent Pay for Machines on 2026-06-10 with more than thirty named partners — production-milestone maturity rather than broad availability, and practitioner commentary from February 2026 still characterized mandate-based flows as early pilots not widely available to consumers. Independent analyses converge on the blockers: merchant liability, dispute management, customer ownership and economics, plus runtime security risks (prompt injection, identity confusion) that demand strict execution-time controls. No genuine empirical head-to-head of these protocols has been published — available comparisons are architectural and largely vendor-authored. Signals suggest network-backed protocols are entering the live-pilot phase, while production adoption waits on liability and dispute frameworks that no protocol has publicly resolved. Google's AP2 — donated to the FIDO Alliance on 2026-04-28, with v0.2.0 adding human-not-present flows — is the major adjacent standard, tracked in our register under a separate discipline.
Caveats
TAP-specific attribution in the European pilot comes primarily from Visa's own materials. Mastercard evidence establishes completed production transactions, not population-scale availability. Pilot-phase readings can move quickly; re-dated on material delta.
