The UK's core instant payment system handling bank-to-bank transfers up to £1M, with most payments arriving in seconds. Originally launched with a £10K limit in 2008, it was one of the world's first real-time retail payment systems. Settles via the Bank of England's RTGS system with net deferred settlement. Managed by Pay.UK, the FPS rail also processes standing orders and forward-dated payments, but the data shown here covers Single Immediate Payments only — the real-time component. The New Payments Architecture (NPA) programme is modernising FPS with ISO 20022 messaging.
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.
