Taiwan's shared interbank real-time rail, operated by FISC (Financial Information Service Co.). Carries both institutional flows and consumer traffic — real-time transfers in every Taiwanese bank's mobile app, any-bank ATM withdrawals, and TWQR merchant payments. TWQR is FISC's national interoperable QR-code standard (launched 2019), used by consumer wallets Line Pay Money, JKO Pay, iPass Money and Pi 拍錢包. Live 24/7 since 1991, connecting 107 institutions, handling TWD plus five foreign currencies (USD, RMB, JPY, EUR, AUD). Settles through the CBC's RTGS.
Mexico's Sistema de Pagos Electrónicos Interbancarios is one of the world's earliest 24/7 real-time payment systems, operated directly by the central bank (Banxico). SPEI processes both high-value and retail payments with no maximum transaction limit, settling in real time through Banxico's accounts. It supports CLABE (standardised 18-digit account numbers) and has been extended with CoDi, a QR-based overlay for merchant payments. Note: SPEI data includes both immediate and scheduled transfers on the same rail, as Banxico does not separately report real-time vs deferred transactions.
