Enabling secure transactions with an underpowered device
Methods, systems, and computer program products for providing secure transactions for a device with limited functionality are disclosed. For example, a computer-implemented method may include presenting an encoded image identifying a form of payment on a display of a computing device in response to detecting a condition limiting a functionality of the device, maintaining the presentation of the encoded image on the display in response to the detected condition, and removing the presentation of the encoded image from the display in response to determining that the detected condition is no longer detected.
1. A mobile device, comprising:
a battery;
a first display of a first display type;
a second display of a second display type different from the first display type;
a non-transitory memory; and
one or more hardware processors coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the mobile device to perform operations comprising:
detecting a condition limiting a display functionality of the first display of the mobile device;
generating an encoded image identifying a form of payment;
in response to detecting the condition, presenting the encoded image on the second display;
maintaining the presentation of the encoded image on the second display for a period of time while the condition exists.
2. The mobile device of claim 1 , wherein the operations further comprise:
determining the condition no longer exists; and
removing the presentation of the encoded image from the second display in response to the determining.
3. The mobile device of claim 1 , wherein the operations further comprise:
determining a location of the mobile device; and
generating the encoded image, at least in part, based on the determined location of the mobile device.
4. The mobile device of claim 1 , wherein the second display comprises a bistable display.
5. The mobile device of claim 1 , wherein the condition comprises a charge of the battery being below a predetermined level.
6. The mobile device of claim 1 , wherein the presenting of the encoded image on the second display of the mobile device is maintained when the mobile device is unpowered.
7. The mobile device of claim 1 , wherein the encoded image comprises at least one machine readable code.
8. The mobile device of claim 1 , wherein the first display is a non-bistable display.
9. The mobile device of claim 1 , wherein the condition comprises a request to shut off the mobile device.
10. A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a mobile device to perform operations comprising:
determining that a power supply level of a battery of the mobile device is below a predetermined threshold;
in response to the determining, activating a display of the mobile device by an encoded image identifying a form of payment on the display of the mobile device; and
maintaining a presentation of the encoded image on the display while the power supply level of the battery remains below the predetermined threshold.
11. The non-transitory machine-readable medium of claim 10 , wherein the operations further comprise:
detecting that the power supply level of the battery is above the predetermined threshold; and
in response to detecting that the power supply level of the battery is above the predetermined threshold, removing the presentation of the encoded image from the display.
12. The non-transitory machine-readable medium of claim 10 , wherein the operations further comprise:
generating the encoded image, at least in part, based on a location of the mobile device.
13. The non-transitory machine-readable medium of claim 10 , wherein the display comprises a bistable display.
14. The non-transitory machine-readable medium of claim 10 , wherein the presenting of the encoded image on the display of the mobile device is maintained when the mobile device is unpowered.
15. A computer-implemented method comprising:
determining, by one or more hardware processors of a computing device, that a power supply level of a battery of the computing device is below a predetermined threshold;
in response to the determining, activating, by the one or more hardware processors, a display of the computing device by presenting an encoded image identifying a form of payment on the display of the computing device; and
maintaining a presentation of the encoded image on the display when the power supply level of the battery remains below the predetermined threshold.
16. The computer-implemented method of claim 15 , further comprising:
detecting, by the one or more hardware processors, that the power supply level of the battery is above the predetermined threshold; and
in response to detecting that the power supply level of the battery is above the predetermined threshold, removing, by the one or more hardware processors, the presentation of the encoded image from the display.
17. The computer-implemented method of claim 15 , further comprising:
generating, by the one or more hardware processors, the encoded image, at least in part, based on a location of the computing device.
18. The computer-implemented method of claim 15 , wherein the display comprises a bistable display.
19. The computer-implemented method of claim 15 , wherein the presentation of the encoded image on the display is maintained when the computing device is unpowered.
20. The computer-implemented method of claim 15 , wherein the encoded image comprises at least one machine readable code.
