Radio frequency identification (RFID) is an automatic identification technology that enables tracking of people and object. In this paper, passive RFID tag is used for indoor localization. Passive RFID tag has many advantages i.e.,cost-effective, relatively small and its endurance.This paper proposes simulation of indoor localization usingself-created Graphic User Interface (GUI) to apply the RFID-based localization using fingerprint technique.In this paper, Maximum number of intersect tags and Maximum and 2nd Maximum number of intersect tags are deployed as pattern matching algorithm. For this technique,the database of fingerprint is obtained from ID information of the tags. The maximum number of intersect tag will be used as the justification of measured position of the target node.The estimated error location is obtained from the location estimation result compared with fingerprint location in the database. Theaverage error in the estimation result for both techniquesis approximately 21 cm. From the results, we can conclude that our proposed method can be applied in real situation.
