Abstract
An electronic device performs near field communication (NFC) functions. An operating method of the electronic device includes detecting an attachment of a first NFC tag which uses a first radio frequency signal type (RF signal type), checking whether to exclude the first NFC tag from a recognition of the NFC device in response to the attachment of the first NFC tag, and when the first NFC tag is excluded from the recognition of the NFC device, setting based on the checking a radio frequency signal type of the electronic device so as not to respond to a radio frequency signal of the first radio frequency signal type.
