Payment Rail

The underlying network infrastructure (ACH, Wire, RTP, FedNow) facilitating funds movement, each with distinct speed, cost, and risk profiles.

Key Details

  • Major US payment rails include ACH (batch, 1-2 day settlement), Wire (real-time, irrevocable), RTP (real-time, 24/7), and FedNow (instant, Federal Reserve operated)
  • Each rail has different cost structures, speed guarantees, reversibility rules, and transaction limits that affect payment routing decisions
  • Card networks (Visa, Mastercard) are payment rails for card-based transactions, with their own settlement cycles and interchange fee structures
  • Cross-border payments involve multiple rails and correspondent banks, creating reconciliation complexity from FX conversion and intermediary fees
  • Payment orchestration layers abstract away rail-specific complexity, routing transactions to the optimal rail based on cost, speed, and availability
