Abstract:
A method for recognizing a tag in an environment where the same frequency band is in use and an NFC device for the same are provided. Depending on whether a radio channel is in use, the NFC device changes a first operation mode to a second operation mode, requests slot assignment for tag recognition at the second operation mode, and changes the second operation mode back to the first operation mode to perform a tag recognition process at an assigned slot.
