A terminal service system and a terminal processing data are disclosed. The terminal service system comprises a terminal and shoe performing data communication with the terminal, wherein the shoe comprises a communication unit for transmitting and receiving a signal to and from the terminal; a sensor unit for sensing first movement data of a user who wears the shoe, through a first sensor; a memory for storing data sensed through the sensor unit; and a controller for controlling turn-on/turn-off of a second sensor on the basis of the first movement data sensed through the first sensor included in the sensor unit to sense second movement data of the user who wears the shoe, and identifying the first movement data sensed through the first sensor from the second movement data sensed through the second sensor to transmit the identified result to the smart terminal, and the smart terminal configures and outputs a user interface on the basis of the first and second movement data transmitted from the shoe.
