The applications of RFID technology are expanding from identification of the tagged objects to localization of real world objects. While previous RFID based localization techniques mainly deal with estimating locations of tags in 1 or 2 dimensions, they do not discuss about estimating sequence among tags. For this purpose, we propose an estimation scheme that utilizes the movement of a RFID reader to find out physical sequence of passive tags. Proposed scheme estimates the sequence among tags based on the changes of tag sets read for each read cycles introduced by a movement of the RFID reader. Proposed scheme can be applied to various applications that utilize physical sequence of tagged objects. Typical applications of proposed scheme can be the automatic verification of tagged objects sequence and the user interface which shows detailed information on tagged objects on a screen according to their physical sequence.
