1. A hybrid tag interface system comprising:
a wireless recognition tag which includes first codes for an object and transmits and receives the first codes through wireless communication;
an image tag which expresses a second code for the object using a 1-dimensional (1D) or 2-dimensional (2D) image;
a tag reader unit which transmits and receives the first codes of the wireless recognition tag and reads the second code of the image tag; and
a tag calculation unit which decrypts the first codes based on a key value for decrypting included in the second code and calculates information on the object from the first codes and the second code based on the correlation between the first codes and the second code.
