The X-ray apparatus 100 according to an embodiment of the present invention can acquire X-ray accumulation amount information of a target object from a target device 200 according to a predetermined short distance wireless communication method.

For example, when the X-ray device 100 and the target device 200 include an NFC module, the NFC module of the X-ray device and the NFC module of the target device can operate in the P2P mode. At this time, the NFC module (client) of the target device 200 accesses the NFC module (host) provided in the X-ray apparatus 100, so that the target device 200 can be tagged by the NFC module provided in the X- And can transmit the X-ray accumulation amount information of the object to the X-ray apparatus 100. [
