Financial transaction systems and methods

A computer-implemented method for facilitating the transfer of funds from a sending account to a receiving account using secure electronic communications, the method including the steps of:

• receiving first data from a first electronic device via a telecommunications network, the first data including:
• partial sending account data representing partial sending account details, wherein the partial sending account details are insufficient to uniquely identify the sending account;
• and
• second electronic device identification data uniquely identifying a second electronic device;
• wherein the first and second electronic devices are capable of sending and receiving messages via the telecommunications network;
• transmitting request data to the second electronic device identified by the second electronic device identification data, via the telecommunications network, at least a portion of the request data being derived from the first data;
• receiving second transaction data representing the remainder of the sending account details required to transfer the funds via the telecommunications network;
• verifying that a source device from which the second transaction data is received is the second electronic device identified by the second electronic device identification data;
• and
• generating combined transaction data from the first transaction data and second transaction data for subsequent transmission to a transaction processor.

A system for facilitating the transfer of funds from a sending account to a receiving account using secure electronic communications, the system including:

• a first message receiving component for receiving a first message from a first electronic device through a message interface, the first message including:
• first transaction data representing partial sending account data representing partial sending account details, wherein the partial sending account details are insufficient to uniquely identify the sending account;
• and
• second electronic device identification data uniquely identifying a second electronic device;
• wherein the first and second electronic devices are capable of sending and receiving messages via a telecommunications network;
• a first message processing component for processing the first message to generate a request message;
• a request message transmitting component for transmitting the request message to the second electronic device identified by the second electronic device identification data;
• a second message receiving component for receiving a second message from the second electronic device identified in the first message through a message interface, wherein the second message receiving component verifies the source of the second message using the second electronic device identification data and identification data embedded in the second message, wherein the second message contains data representing the remainder of the sending account details required to transfer the funds;
• and
• a message combining component for combining information in the first message with information in the second message to generate combined transaction data for transmission to a transaction processor.
