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.
Brazil's instant payment system created by the central bank, supporting P2P, P2B, B2B, QR codes, and bill payments. Pix reached 160M+ users within 3 years of launch, making it one of the fastest-adopted payment systems in history. Transactions are free for individuals, settle in under 10 seconds 24/7, and can be initiated via QR code, CPF/CNPJ tax ID, phone number, or email. Pix has largely replaced cash, boletos, and card-based debit in everyday Brazilian commerce.
