The Federal Reserve's instant payment service enabling US banks and credit unions to send and receive payments in seconds, 24/7/365. Launched in July 2023, FedNow is the first new Fed payment rail in 50 years and aims to democratise instant payments by giving all 10,000+ US depository institutions direct access (unlike the private-sector RTP). Supports credit transfers up to $500K with plans to add request-for-payment and other features. Note: FedNow shows extreme growth rates as it scales from a low base — value jumped 35x in Q3 2024 as larger institutions onboarded, which is typical for newly launched payment systems.
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.
