Wireless terminal and RFID system for providing additional information and a method for providing additional information using wireless terminal and RFID system
First Claim
1. A wireless terminal for providing additionalinformation, 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.

Abstract
A wireless terminal and a radio frequency identification system for providing additional information and a method of providing additional information using the wireless terminal and the radio frequency identification system. The wireless terminal includes: a tag reader reading tag data from a radio frequency identification tag; a controller generating an additional information request signal with respect to the read tag data; and a communication network interface transmitting the additional information request signal through a communication network and receiving additional information with respect to the additional information request signal. Since the controller of the wireless terminal controls the radio frequency identification reader by optimally setting the information required for determining the time point for the radio frequency identification reader tag to respond, and utilizing the stored address of the additional information providing server, the additional information can be efficiently provided.
