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.
Sweden's dominant mobile payment app used by 8M+ people (in a country of 10.5M) for P2P transfers, in-store payments, and e-commerce. Swish transactions clear through the Bankgirot Immediate Payments (BIR) real-time clearing system. Founded by six major Swedish banks, Swish has been a key driver of Sweden's shift toward a nearly cashless society. Payments are initiated via phone number and settle instantly, with merchant payments supported via QR codes and Swish for Business.
