C. Gaps / Unknowns

  • Exact timeline and technical specifications for UK domestic card scheme (stated as 2030 target; architecture TBD)
  • Details on HM Treasury's PSR consolidation into FCA (proposed 2025-2026; not yet finalized)
  • Merchant fee structures and interchange rates for Faster Payments vs. card networks (proprietary; varies)
  • Complete list of all FCA-authorized PISPs and detailed market share distribution (rapidly growing; list changes monthly)
  • ATM network coverage and trajectory of branch closures (ongoing; data delayed)
  • Real-time settlement finality timing for Faster Payments (typically seconds, but not guaranteed SLA)
  • Detailed technical specifications for Bank of England's extended CHAPS hours implementation (H2 2027 target)
  • Post-Brexit impact on cross-border payment corridors with EU/EEA (ongoing adjustment; varied by corridor)

D. Audit Notes

  • CHAPS, Faster Payments, and Bacs are the three primary clearing schemes; all operated by Pay.UK
  • CHAPS is RTGS-based (real-time, same-day, high-value); Faster Payments is instant 24/7 (lower individual limits); Bacs is batch 3-day (low-cost, high-volume)
  • Open Banking (PSD2) is regulatory framework enabling PISPs; not a payment system itself—the PISPs (Stripe, TrueLayer, Wise, Revolut, GoCardless, etc.) operate the payment services
  • LINK is ATM network operator; not a payment system per se, but infrastructure for cash access
  • Paym was closed March 2023; functionality replaced by Open Banking and other P2P apps; should not be listed as active
  • Visa/Mastercard/Amex are international card networks, not UK domestic schemes
  • UK Domestic Card Scheme is in development (planned 2030); not yet operational
  • Apple Pay, Google Pay, Samsung Pay are app-layer wrappers on Visa/Mastercard/debit rails; not independent payment systems
  • Revolut, Wise, Monzo, Starling, N26 are fintech apps leveraging FPS/Open Banking rails; not independent clearing systems
  • ClearBank is critical fintech infrastructure enabling third-party access to payment rails
  • Banking Hubs are response to branch closures; operate on underlying Bacs/bank settlement
  • SWIFT is cross-border messaging only (not domestic)
  • Payments Vision Delivery Committee published long-term infrastructure strategy November 2025 (critical policy document)
