Other forms of electronic transfers include, for example, electronic funds transfer system (EFTS). This is the system used to transfer money from a bank account to another party. It is also the system used in some payments made via a bank's online bill payment service. These transfers are made using a bank routing number and the account number at that institution. EFTS transfers differ from wire transfers in important legal ways. An EFTS payment is essentially an electronic personal check, whereas a wire transfer is more like an electronic cashier's check.
