Proximity peer to peer mobile navigation system and method

A non-transitory computer readable medium storing software comprising instructions executable by one or more computers, which, upon such execution, cause the one or more computers to:

• register a first mobile communication device with a service provider configured to coordinate electronic transfer of currency between accounts of two different users;
• determine a first location of the first mobile communication device at a venue;
• transmit a beacon from the first mobile communication device to one or more other mobile communication devices at the venue, wherein the beacon includes a message requesting a cash payment of a first amount;
• receive, at the first mobile communication device, a response message to the message requesting cash payment included in the transmitted beacon from a second mobile communication device of the one or more other mobile communication devices at the venue, wherein the second mobile communication device is also registered with the same service provider as the first mobile communication device;
• establish a peer to peer communication between the first mobile communication device and the second mobile communication device based on the response message;
• receive, at the first mobile communication device, a second location of the second mobile communication device at the venue from the second mobile communication device;
• access a map of the venue, which includes the first location and the second location, and display the map on a display of the first mobile communication device;
• display a first icon indicating the first location and a second icon indicating the second location on the map of the display of the first communication device;
• determine and display one or more routes between the first location and the second location on the displayed map of the venue on the first mobile communication device;
• wherein, when the first mobile communication device is located at the second location at the venue, conduct a transaction between the first mobile communication device and the second mobile communication device to exchange an electronic transfer of currency for the cash payment of the first amount;
• wherein, prior to conducting the transaction between the first mobile communication device and the second mobile communication device, the service provider requires that both the first mobile communication device and the second mobile communication device provide respective private keys for a mutual authentication to the service provider in order to conduct the transaction, each private key enabling a user associated with a respective mobile communication device to sign information to conduct the transaction, the private keys each being obtained by the respective mobile communication device by using biometric information from the respective user associated with the respective mobile communication device to unlock a respective vault hosted by a trusted third party containing the respective private key;
• and
• wherein, after the private keys for the mutual authentication from both the first mobile communication device and the second mobile communication device are received by the service provider, the service provider coordinates the electronic transfer of currency between an account of a first user associated with the first mobile communication device to an account of a second user associated with the second mobile communication device to conduct the transaction.

A system of locating mobile communication devices in a peer to peer communication using a beacon at a venue, the system comprising:

• a wireless network coupled to a plurality of base stations at the venue;
• a first mobile communication device located at the venue, the first mobile communication device configured to determine a first location of the first mobile communication device at the venue and to transmit a beacon to one or more other mobile communication devices at the venue, wherein the beacon includes a message requesting a cash payment of a first amount, the first mobile communication device being coupled to the wireless network though one of the plurality of base stations;
• and
• a second mobile communication device of the one or more other mobile communication devices at the venue, the second mobile communication device configured to determine a second location of the second mobile communication device at the venue and to receive the beacon from the first mobile communication device, the second mobile communication device being coupled to the wireless network though one of the plurality of base stations;
• a service provider configured to coordinate electronic transfer of currency between accounts of two different users, wherein the first mobile communication device and the second mobile communication device are both registered with the service provider;
• the first mobile communication device being further configured to receive a response message to the message requesting cash payment included in the transmitted beacon from the second mobile communication device, and to establish a peer to peer communication with the second mobile communication device based on the response message;
• the second mobile communication device being configured to transmit the second location of the second mobile communication device at the venue to the first mobile communication device;
• and
• the first mobile communication device being configured to:
• access a map of the venue, which includes the first location and the second location, and display the map on a display of the first mobile communication device;
• display a first icon indicating the first location and a second icon indicating the second location on the map of the display of the first mobile communication device;
• determine and display one or more routes between the first location and the second location on the displayed map of the venue on the first mobile communication device;
• wherein, when the first mobile communication device is located at the second location at the venue, the first mobile communication device is configured to conduct a transaction between the first mobile communication device and the second mobile communication device to exchange an electronic transfer of currency for the cash payment of the first amount;
• wherein, prior to conducting the transaction between the first mobile communication device and the second mobile communication device, the service provider requires that both the first mobile communication device and the second mobile communication device provide respective private keys for a mutual authentication to the service provider in order to conduct the transaction, each private key enabling a user associated with a respective mobile communication device to sign information to conduct the transaction, the private keys each being obtained by the respective mobile communication device by using biometric information from the respective user associated with the respective mobile communication device to unlock a respective vault hosted by a trusted third party containing the respective private key;
• and
• wherein, after the private keys for the mutual authentication from both the first mobile communication device and the second mobile communication device are received by the service provider, the service provider coordinates the electronic transfer of currency between an account of a first user associated with the first mobile communication device to an account of a second user associated with the second mobile communication device to conduct the transaction.
