"Modern Treasury today announced that its Payment Service Provider (PSP) now supports payments via physical and digital checks. Rather than integrating a separate check printing vendor or maintaining distinct reconciliation workflows, developers can use a single API to route payments across ACH, wires, RTP, FedNow, push-to-card, stablecoins, physical checks, and digital checks. The result is less operational complexity, faster implementation, and consistent payment tracking across every rail."
