In Indonesia, bank transfer methods account for nearly 25% of all online purchases, representing an estimated e-commerce volume of around US$5.75 billion. Consumers can easily make these payments by entering a 16-digit payment code, also referred to as a Virtual Account Number. Payments can be processed through internet banking or at the ATMs of participating banks. Key supported ATM networks include Bersama, Prima, and Alto, while notable banks that facilitate these transactions include Bank Danamon, Bank Mandiri, Bank Negara Indonesia, CIMB Niaga, Permata Bank, and Maybank Indonesia.
