Electronic transfers are common. But electronic payments like that are not so much. We have Bank QR codes and something simillar to M-Pesa, but its not that widespread because there is no one standard for QR payments or similar. That makes it less practical to use because both you and the vendor must use the same bank. (El Salvador is small and there are many finatial instituions.) Something like U.S. Zelle or Swedish Swish would help, but banks have not standardized yet. If WhatsApp started something like WeChat payments it would become a hit. Like they did in Brazil.
