Abstract:
A system and method for protecting private information by using a near field communication (NFC) tag is provided. A method of making a call by using a telephone number received from a near field communication (NFC) tag in a device includes: receiving from the NFC tag a telephone number and call limit information related to the telephone number according to an approach to the NFC tag; determining whether a call to a target device having the received telephone number is limited based on the call limit information; and limiting a call to the target device based on the determination.
