METHOD FOR RETRIEVING INFORMATION TABLE OF A RFID-TAG EMBEDED PRODUCT

摘要

PURPOSE: A method for searching RFID(Radio Frequency Identification) product information is provided to improve searching performance by executing connection search without using a reference table. CONSTITUTION: A product location information stored using a predetermined code system is searched from a history table(S10). Another product location information which is stored using a similar code system with the product location information of the history table is searched from a state information table(S20). The predetermined information is searched from the history or state information table using index field connected to the product location information including the similar code system(S40). The code system is composed of a business, a building, and a detailed location code. [Reference numerals] (S10) Product location information of a serialized global location number code system is searched from a history information table; (S20) The product location information of the serialized global location number code system is searched from a state information table; (S30) The product location information of the history information table is compared with the location information of the state information table; (S40) Desired information is searched from the history information table or the state information table using a connection index filed in the same code system and the same information values
