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.
Japan's domestic interbank clearing network, one of the oldest electronic payment systems in the world, connecting over 1,000 banks. Originally batch-only; upgraded to 24/7 real-time in 2018 via the More Time System. Underpins consumer real-time transfers in every Japanese bank's mobile app, any-bank ATM transfers, and the bank-funding legs of major consumer wallets (PayPay, LINE Pay, Rakuten Pay, au PAY). Operated by the Japanese Bankers Association with settlement through the BOJ. Note: data includes all Zengin transactions (real-time and batch-processed).
