Systems and methods for secure wireless payment transactions when a wireless network is unavailable
Systems, methods, and devices are disclosed which allow a mobile device user to complete financial transactions even when the mobile device is not connected to a wireless network. The systems, methods, and devices of the present disclosure may utilize a combination of an encrypted lockbox containing out of network payment codes on the mobile device and a matching set of out of network payment codes stored on a server of a payment authority.
1. A method for conducting a transaction using a mobile device, comprising:
executing an application with a digital lockbox on the mobile device;
receiving a request from a user using the application for a payment code at the mobile device;
determining that a wireless network is unavailable to the mobile device;
retrieving an out-of-network payment code from the digital lockbox of the mobile device in response to the determination that the wireless network is unavailable, the out-of-network payment code associated with a state of disconnectivity between the mobile device and the wireless network is only to be used by the mobile device when the wireless network is unavailable;
providing the retrieved out-of-network payment code to a point of sale terminal to authorize the transaction; and
communicating, using the application, with a payment authority server to receive a replacement out-of-network payment code for the digital lockbox in response to the mobile device reconnecting to the wireless network.
2. The method of claim 1 , wherein retrieving the out-of-network payment code from the digital lockbox comprises:
decrypting the digital lockbox to access the out-of-network payment code.
3. The method of claim 1 , wherein providing the retrieved out-of-network payment code to the point of sale terminal comprises:
providing the out-of-network payment code to the point of sale terminal via Near Field Communications (NFC) circuitry.
4. The method of claim 1 , wherein providing the retrieved payment code to the point of sale terminal comprises:
displaying the out-of-network payment code to the user of the mobile device.
5. The method of claim 1 , wherein providing the retrieved out-of-network payment code to the point of sale terminal comprises:
providing an unknown portion of the retrieved out-of-network payment code to the user of the mobile device for combination with a portion of the retrieved out-of-network payment code known to the user.
6. The method of claim 1 , further comprising: removing the retrieved out-of-network payment code from the digital lockbox following authorization of the transaction.
7. The method of claim 1 , further comprising:
adjusting a set period of validity of at least one out-of-network payment code stored in the digital lockbox based on a location of the mobile device.
8. The method of claim 1 , wherein at least one out-of-network payment code stored in the digital lockbox is valid indefinitely.
9. A system for conducting a transaction, comprising:
a mobile device; and
an application with a digital lockbox executed on the mobile device, wherein the application comprises executable code that, when executed causes the mobile device to:
determine that a wireless network is unavailable to the mobile device upon receipt of a request from a user for a payment code;
retrieve an out-of-network payment code from the digital lockbox of the mobile device in response to the determination that the wireless network is unavailable, the out-of-network payment code associated with a state of disconnectivity between the mobile device and the wireless network and is only to be used by the mobile device when the wireless network is unavailable;
provide the retrieved out-of-network payment code to a point of sale terminal to authorize the transaction; and
communicate with a payment authority server to receive a replacement out-of-network payment code for the digital lockbox in response to the mobile device reconnecting to the wireless network.
10. The system of claim 9 , wherein to retrieve the out-of-network payment code from the digital lockbox comprises:
to decrypt the digital lockbox to access the out-of-network payment code.
11. The system of claim 9 , wherein to provide the retrieved out-of-network payment code to the point of sale terminal comprises:
to provide the out-of-network payment code to the point of sale terminal via Near Field Communications (NFC) circuitry.
12. The system of claim 9 , wherein to provide the retrieved payment code to the point of sale terminal comprises:
to display the out-of-network payment code to the user of the mobile device.
13. The system of claim 9 , wherein to provide the retrieved out-of-network payment code to the point of sale terminal comprises:
to provide an unknown portion of the retrieved out-of-network payment code to the user of the mobile device for combination with a portion of the retrieved out-of-network payment code known to the user.
14. The system of claim 9 , wherein the application comprises executable code that, when executed further causes the mobile device to:
remove the retrieved out-of-network payment code from the digital lockbox following authorization of the transaction.
15. The system of claim 9 , wherein the application comprises executable code that, when executed further causes the mobile device to:
adjust a set period of validity of at least one out-of-network payment code stored in the digital lockbox based on a location of the mobile device.
16. The system of claim 9 , wherein at least one out-of-network payment code stored in the digital lockbox is valid indefinitely.
