Abstract:
1. A wireless terminal for providing additional information, comprising: a tag reader which reads tag data from a radio frequency identification tag; a controller which generates an additional information request signal with respect to the read tag data; a communication network interface which transmits the additional information request signal through a communication network and receives the additional information in response to the additional information request signal; and a memory which stores a tag data list comprising the tag data and address information of an additional information providing server corresponding to the tag data; wherein if the tag data list does not comprise the data coinciding with the read tag data according to the result of comparing the tag data with the tag data list, the controller generates an address information request signal, transmits the address information request signal through the communication network interface to an address information providing server, and generates the additional information request signal using the address information transmitted from the address information providing server.
