Abstract: A method for identifying information on an external electronic device based on near field communication (NFC). The method includes transmitting a signal of an NFC band to the external electronic device; identifying whether the external electronic device is capable of NFC, requesting an NFC identifier (ID) from the external electronic device, and receiving the NFC ID from the external electronic device; receiving the NFC ID, reading a unique identifier from the NFC ID, and identifying a communication protocol type; identifying flag information included in the NFC ID; and determining whether the external electronic device is initially recognized and/or normally recognized through the flag information.
