Smart card and method for controlling the same
First Claim
1. A smart card comprising:
- a sensor configured to sense a finger touch; and
a controller configured to;
cause a first setting change by setting the smart card from a default payment method to a selected payment method selected by a user, when a fingerprint of the user is recognized based on the finger touch sensed by the sensor;
cause a second setting change by setting the smart card from the selected payment method to the default payment method when the fingerprint of the user and a fingerprint of a first person other than the user are simultaneously recognized and a first preset time elapses after completion of payment using the selected payment method; and
cause a third setting change by setting the smart card from the default payment method to the selected payment method when the fingerprint of the user and the fingerprint of the first person are simultaneously recognized again within a second preset time.

Abstract
The present invention relates to a smart card including a sensor for sensing a finger touch and a controller for causing a first setting change by setting the smart card from a default payment method to a selected payment method, when a fingerprint of the user is recognized based on the finger touch sensed by the sensor; causing a second setting change by setting the smart card from the selected payment method to the default payment method when the fingerprint of the user and a fingerprint of a first person other than the user are simultaneously recognized and a first preset time elapses after completion of payment, and causing a third setting change by setting the smart card from the default payment method to the selected payment method when the fingerprint of the user and the fingerprint of the first person are simultaneously recognized again within a second preset time.

13. A method for controlling a smart card, the method being performed by a processor and comprising:
-
sensing, with a sensor, a finger touch to the smart card, wherein the sensor is configured to sense the finger touch to the smart card; causing, by the processor, a first setting change by setting the smart card from a default method to a selected method selected by a user when a fingerprint of the user is recognized based on the finger touch; causing, by the processor, a second setting change by setting the smart card from the selected method to the default method when the fingerprint of the user and a fingerprint of a first person other than the user are simultaneously recognized by the sensor and a first preset time elapses after completion of transaction using the selected method; and causing, by the processor, a third setting change by resetting the smart card from the default method to the selected method when the fingerprint of the user and the fingerprint of the first person are simultaneously recognized again within a second preset time. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
