Embodiments of the present invention utilize audio messages to initiate, process and complete transactions between two or more parties, allowing users to efficiently and effectively enter into and complete financial transactions with businesses and other users. The need to utilize text-based entry as part of the verification process—an inefficient, error-prone and insecure authorization mechanism—is minimized and, in some embodiments, avoided altogether. Unlike recently developed authorization methods, embodiments of the present invention may be implemented using any number of existing devices including, analog or digital televisions, radios, smartphones, tablets computers, and other devices. Embodiments of the present invention may also be utilized to facilitate authorization for various other transactions including to access to an account, website or other locations, to accept or propose trades, to sign a legal or non-legal document, and to verify identity. ## Claims ### Claim 1 A method of authorizing an electronic transaction, the method comprising: communicating to a request-emitting system a request signal containing an encoded audio request message, said request signal causing the encoded audio request message to be outputted at the request-emitting system for receiving by a receiving device, wherein the outputted encoded audio request message causes the receiving device to: automatically decode the encoded audio request message, the decoded audio request message containing a request identifier;

generating an encoded complementary audio message containing complementary information to the authorization request; and communicating to the request-emitting system a complementary message containing the encoded complementary audio message, said complementary message causing the encoded complementary audio message to be outputted at the request-emitting system. ### Claim 13 (depends on 12) The method of claim 12, wherein the receiving device receives a complementary response from the user responsive to the complementary information, and wherein the authorization response includes the complementary response. ### Claim 14 (depends on 1) The method of claim 1, wherein the authorization request comprises at least one of a logical or physical access request, an electronic fund transfer request as a payment request, a user data request, a poll request, an agreement request, an enrollment request and a hardware triggering request. ### Claim 15 A method of processing an authorization request at a mobile device containing a processor and memory, the mobile device capable of receiving and processing encoded audio messages, the method comprising: receiving an encoded audio authorization request, said authorization request containing a request identifier; recording the encoded audio authorization request to process the authorization request; decoding, using the processor, the authorization request to provide at least a portion of the decoded authorization request to a user; receiving a request authorization from the user; generating, using the processor, an authorization response containing the request authorization and the request identifier; and transmitting the authorization response to provide authorization. ### Claim 16 (depends on 1) The method of claim 1, wherein the encoded audio authorization request comprises at least one of audible and inaudible tones. ### Claim 17 (depends on 1) The method of claim 1, further comprising the step of determining, using the processor, whether the encoded audio authorization request is a valid encoded audio authorization request according to at least one authorization rule stored in memory. ### Claim 18 (depends on 1) The method of claim 1, wherein at least one authorization rule is based at least on the physical location of the mobile device, the identity of the device, or the identity of the user. ### Claim 19 (depends on 1) The method of claim 1, wherein the encoded audio authorization request is encoded based on a unique decoding key, said mobile device having access to the unique decoding key, and wherein the encoded audio authorization request is decoded based on the unique decoding key. ### Claim 20 A system for facilitating the authorization of electronic transactions, the system comprising: a processor;
