A wearable band comprises a first near field communication (NFC) module, a second NFC module, and a band controller. The first NFC module includes an NFC reader reading first tag information from a first NFC tag, and the second NFC tag. The second NFC tag performs near filed communications with a terminal in charge. The band controller prepares NFC data for transmission through the second NFC module. The NFC data can be notification information for the terminal in charge, request information, or transmission information generated by at least a part of the first tag information. |
