Abstract: An electronic fund transfer system comprises a transaction server, a first mobile electronic device operated by a first user, and a second mobile electronic device operated by a second user. The transaction server stores user profiles, including financial account details and other personal details, for each of the first user and the second user, and further stores therein a list of first users associate with a premise. The second mobile electronic device is operable to obtain from the transaction server the list of first users associated with the premise. The second mobile electronic device is further operable by the second user to select one first user from the list and effect a transfer of funds from the second user to the selected first user. The transfer of funds from the second user to the selected first user is effected without any of the financial account details and other personal details of the first user being provided to the second user.
