Method and apparatus for performing payment function in limited state
A user terminal supporting mobile payment service is provided. The user terminal includes a display, a memory in which a payment application is stored, and a processor configured to run the payment application. If at least one specified user input occurs on the display while in a locked state, the processor runs the payment application without unlocking the locked state. Thus the payment application may be quickly launched from the locked state.
1. An electronic device comprising:
a sensor;
a display comprising a touch panel and a layer for displaying content;
a memory storing a payment application; and
a processor configured to:
while the electronic device operates in a screen-off state, receive a swipe input spanning from a first predesignated region of the display to a second predesignated region of the display or a third predesignated region of the display,
in response to detecting that the swipe input ends on the second predesignated region, maintain the screen-off state, or
in response to detecting that the swipe input ends on the third predesignated region:
execute the payment application,
display, on the display, an image of a card which is registered on the payment application together with an instruction for prompting a biometric input,
obtain, through the sensor, biometric information used for user authentication, and
transmit, a payment signal via the payment application,
wherein while the electronic device operates the screen-off state, power supplied to the layer is cut off and power supplied to the touch panel is maintained.
2. The electronic device of claim 1 , wherein the processor is further configured to:
display, at a side of the display, at least part of another image of another card registered on the payment application.
3. The electronic device of claim 1 , wherein the processor is further configured to:
apply a blur effect to a background screen of the display.
4. The electronic device of claim 1 , further comprising a touch sensor included in the display, and
wherein the processor is further configured to:
while the electronic device operates in the screen-off state, control the display not to output a screen, and
control the touch sensor to sense the swipe input periodically.
5. The electronic device of claim 1 ,
wherein the biometric information comprises fingerprint information.
6. The electronic device of claim 1 ,
wherein the payment signal comprises a Near Field Communication (NFC) signal or a Magnetic Secure/Signal Transmission (MST) signal.
7. The electronic device of claim 1 , further comprising a proximity sensor, and
wherein the processor is further configured to:
detect, through the proximity sensor, whether another object is located within a certain distance from the electronic device, and
when the another object is located within the certain distance, not execute the payment application.
8. The electronic device of claim 1 , further comprising an illumination sensor, and
wherein the processor is further configured to:
detect brightness through the illumination sensor, and
when the brightness is lower than a specified level, not execute the payment application.
9. The electronic device of claim 1 , wherein the swipe can start from any point in the first predesignated region and end at any point in the second predesignated region.
10. An electronic device comprising:
a display comprising a touch panel and a layer for displaying content;
a memory storing a payment application; and
a processor configured to:
while the electronic device operates in a screen-off state, receive a swipe input spanning from a first predesignated region of the display to a second predesignated region of the display or a third predesignated region of the display,
in response to detecting that the swipe input ends on the second predesignated region, maintain the screen-off state, or
in response to detecting that the swipe input ends on the third predesignated region:
execute the payment application,
display, on the display, an image of a card which is registered on the payment application,
transmit, a payment signal via the payment application,
wherein while the electronic device operates the screen-off state, power supplied to the layer is cut off and power supplied to the touch panel is maintained.
11. The electronic device of claim 10 , wherein the processor is further configured to:
display, at a side of the display, at least part of another image of another card registered on the payment application.
12. The electronic device of claim 10 , wherein the processor is further configured to:
apply a blur effect to a background screen of the display.
13. The electronic device of claim 10 , further comprising a touch sensor included in the display, and
wherein the processor is further configured to:
while the electronic device operates in the screen-off state, control the display not to output a screen, and
control the touch sensor to sense the swipe input periodically.
14. The electronic device of claim 10 , wherein the payment signal comprises a Near Field Communication (NFC) signal or a Magnetic Secure/Signal Transmission (MST) signal.
15. The electronic device of claim 10 , further comprising a proximity sensor, and
wherein the processor is further configured to:
detect, through the proximity sensor, whether another object is located within a certain distance from the electronic device, and
when the another object is located within the certain distance, not execute the payment application.
16. The electronic device of claim 10 , further comprising an illumination sensor, and
wherein the processor is further configured to:
detect brightness through the illumination sensor, and
when the brightness is lower than a specified level, not execute the payment application.
17. A method of an electronic device, comprising:
while the electronic device operates in a screen-off state, receiving a swipe input spanning from a first predesignated region of a display to a second predesignated region of the display or a third predesignated region of the display;
in response to detecting that the swipe input ends on the second predesignated region, maintaining the screen-off state; or
in response to detecting that the swipe input ends on the third predesignated region:
executing a payment application,
displaying, on the display, an image of a card which is registered on the payment application together with an instruction for prompting a biometric input,
obtaining biometric information used for user authentication, and
transmitting, a payment signal via the payment application,
wherein while the electronic device operates the screen-off state, power supplied to a layer for displaying content is cut off and power supplied to a touch panel of the display is maintained.
18. The method of claim 17 , further comprising:
displaying, at a side of the display, at least part of another image of another card registered on the payment application.
19. The method of claim 17 , further comprising:
applying a blur effect to a background screen of the display.
20. The method of claim 17 , further comprising:
detecting whether another object is located within a certain distance from the electronic device, and
when the another object is located within the certain distance, not executing the payment application.
21. The method of claim 17 , further comprising:
detecting brightness through an illumination sensor, and
when the brightness is lower than a specified level, not executing the payment application.
