Immediate Payment Service is India's original 24/7 real-time interbank transfer system launched by NPCI, and the foundational infrastructure that UPI was later built upon. IMPS uses MMID (Mobile Money Identifier) and mobile number for addressing, supports transfers up to INR 5 lakh, and connects banks via the National Financial Switch. While UPI has overtaken it for consumer payments, IMPS remains widely used for direct bank-to-bank transfers and backend settlement.
Australia's New Payments Platform is a real-time clearing and settlement infrastructure with the Osko overlay service for consumer-facing instant transfers. PayID lets users receive money via phone number, email, or ABN instead of BSB/account numbers. Built on ISO 20022 messaging from day one, NPP supports rich data payloads and is governed by NPPA with 100+ participating financial institutions. Note: NPP data includes all overlay services (Osko, PayTo, and other mandated payment services) — not just real-time consumer transfers.
