Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a wireless authentication apparatus for identifying a counterfeit product according to the present invention. The wireless authentication apparatus for identifying a counterfeit product according to the present invention has master key data and an operator, A recognition module 110 for performing an encryption operation on the input authentication key data to generate an encrypted code; An NFC tag chip 120 connected to the recognition module 110 to transmit and receive the authentication key data and the encrypted code in an NFC (Near Field Communication) system; And an NFC antenna 130 connected to the NFC tag chip 120 to receive the authentication key data and transmit the encrypted code.

Here, the NFC tag chip 120 is a non-contact type short-range wireless communication module using a frequency band of 13.56 MHz and is an electronic tag chip performing NFC communication within a distance of about 10 cm or less.

The recognition module 110 is a chip type having master key data and an operator, which are manufactured at a semiconductor wafer level.
