A mobile device and method for performing a function using a short-range communication tag are provided. In the method, the mobile device inputs function-related information into a short-range communication tag, and recognizes proximity to or contact with the short-range communication tag. Then the mobile device reads the function-related information from the short-range communication tag, and performs a function correlated with the function-related information. This allows performing various functions of the mobile device, only depending on a user's action to bring the mobile device in proximity to or contact with the Near Field Communication (NFC) tag.
