AUXILIARY IMAGING DEVICE FOR NFC TERMINAL DEVICE AND METHOD THEREOF

摘要

According to an embodiment of the present invention, an auxiliary imaging device for a near field communication (NFC) device may include: an NFC bridge circuit capable of communicating wirelessly with an NFC terminal device; a holder in which the NFC terminal device can be held; and a camera shutter button which is connected to the NFC bridge circuit wire. The NFC bridge circuit may include: a loop antenna capable of being supplied with power wirelessly from the NFC terminal device; a processor which is operated by the power and produces first shutter-on data when a user pushes the shutter button; and an NFC module which is operated by the power and transfers first wireless signals corresponding to the first shutter-on data to the NFC terminal device. By a camera application program executed in the NFC terminal device, an image of the time when the first shutter signals corresponding to the first wireless signals are received is photographed.
