Payment Journey Mapper renders interactive flow diagrams for four major A2A payment rails, with annotatable steps and a failure-point overlay.
FedNow Credit: The Federal Reserve's instant credit push rail (live since 2023), settling in under 20 seconds 24/7/365.
ACH Debit: NACHA's batch debit rail. Same-Day ACH settles in hours; standard ACH in 1–3 business days.
UK Open Banking: PISP-initiated Faster Payments using PSD2/OBIE standards. Sub-2-second settlement.
SEPA Instant (SCT Inst): EPC's pan-European instant credit scheme. Maximum €100,000 per transaction, 10-second settlement.
The failure overlay highlights documented failure modes at each step: including reversal risks, reference mismatches, timeout scenarios, and compliance blocks: with mitigation guidance.
All diagram state can be shared via the URL (template + overlay settings encoded as query parameters). No data leaves your browser.
