    Abstract: A method and apparatus for security of communication devices that communicate with each other in a near field are provided. A Near Field Communication (NFC) security apparatus may detect the presence of a neighboring device other than communication devices, based on a change in a near field. In response to detecting the presence of the neighboring device, the NFC security apparatus may control an amount of energy transmitted by the communication devices such that the neighboring device may be prevented from accurately receiving a signal transmitted between the communication devices.
