A watch-type mobile terminal comprising:
- a touchscreen;
- a power supply unit;
- a main body;
- a band connected to the main body and configured to be worn on a user's wrist;
- an antenna having at least one turn such that a Near Field Communication (NFC) signal for acquiring product information from a product proceeds toward a user's hand, and arranged along a circumference of the band through the main body;
- and
- a controller configured to:
- control the power supply unit to change power applied to the antenna in order to reduce a strength of the NFC signal when a plurality of product information is acquired from a plurality of products, wherein the strength of the NFC signal is reduced such that product information of only one of the plurality of products is acquired;
- determine that an error occurs when product information is acquired from more than one of the plurality of products;
- control the power supply unit to further reduce the strength of the NFC signal when the error occurs;
- determine that no error occurs when the product information is acquired from the only one of the plurality of products that is located at the user's hand;
