The first modern US instant payment system, operated by The Clearing House (owned by 22 of the largest US banks). RTP launched in 2017 and supports credit transfers up to $1M with immediate finality — no chargebacks or returns. It also offers Request for Payment (RfP) messaging for bill pay and invoicing. While FedNow provides Fed-backed infrastructure, RTP has a head start with broader bank connectivity and higher transaction limits, and processes the majority of US instant payment volume today.
Argentina's Sistema Nacional de Pagos enables instant interbank transfers supporting both push (credit) and pull (debit) payments via CBU (bank account), CVU (virtual wallet), or alias (human-readable name). Operated by the BCRA, it connects traditional banks and the rapidly growing fintech/e-wallet ecosystem (Mercado Pago, Ualá, etc.). Transferencias 3.0 extended the system with interoperable QR codes for merchant payments, making it one of Latin America's most feature-rich instant payment platforms.
