Real time verification of transfers of funds

A system comprising:

• one or more processors;
• and
• one or more machine readable media including instructions, which when executed by the one or more processors, cause the one or more processors to:
• receive a first request to verify a first requested transfer of funds from a first account to a first merchant prior to the first merchant receiving an acceptance of the first requested transfer of funds;
• identify a first instance of an application program installed on a first mobile wireless device as being associated with the first account;
• cause, in response to receiving the first request, a first notification of the first requested transfer of funds to be presented on the first mobile wireless device via the first instance of the application program;
• determine that the first requested transfer of funds is not approved by a user of the account based on a first message received from the first instance of the application program or a failure to receive a message from the first instance of the application program within a predetermined period of time;
• and
• cause use of the first account to be disabled in response to the determination that the first requested transfer of funds is not approved by a user of the account.
