Hong Kong's Faster Payment System enables 24/7 real-time transfers in both HKD and RMB between banks and stored-value facilities. Uniquely dual-currency by design, it supports proxy-based addressing via mobile number, email, or FPS ID. Operated by HKMA with settlement through the CHATS RTGS system, it has become the backbone of Hong Kong's digital payment ecosystem with 12M+ registrations.
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.
