In México, we have SPEI. Allows free instant transfers between bank accounts (with some exceptions). We employ an 18-digit code (CLABE), and debit card numbers are also permitted. You can add a phone number to your bank account to receive money transfers with it. SPEI supports push and pull, the latter being less common. SPEI can be utilized to remit payment for certain credit cards and specialized services. CLABE 18-digit codifies the bank, account location, account number and a verify digit. SPEI is managed by a subsidiary of the Mexican central bank. For a country where many things work slow a clunky, SPEI woks surprisingly well and fast. We really missed it when we tried to send money outside of Mexico.
