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.
The Philippines' real-time low-value electronic fund transfer system, part of the BSP's National Retail Payment System (NRPS) framework. InstaPay handles instant transfers up to PHP 50,000 between banks, e-money issuers (GCash, Maya), and rural/thrift banks via account number or mobile number. Complemented by PESONet for higher-value batch transfers, InstaPay has been a key driver of the Philippines' push toward digital payments with the BSP targeting 50% of transactions to be digital by 2025.
