This paper proposed to recognize and tracking the ID and location when a person and objects moved from indoor using RFID a type of passive tag. An antenna was installed in both sides of a door due to the limitation of a recognition distance. And frequency bandwidth was used to the 134.2㎑ bandwidth to pass and bend several obstacles. Because a type of passive tag is a semi-permanent and miniaturization, it has applied to this paper.

In this paper, it has a proposal of the RFID(RFID : Radio Frequency Identification) system for high-speed recognition between the tag attached a mobile object moving high-speed and the static reader. It used 13.56㎒ frequency at ISM band, and designed a reader in order to recognize a mobile object moving high-speed. It will be expected that RFID system enables a smooth railway signal control applying in railway system through the cyclic loop antenna.

In this paper, it is proposed instruction code satisfied algorithm that is able to prevent data collision when transponder access in the area of recognition system that is operated to single channel. Differ from absolute collision is used to in the time domain procedure, instruction code satisfied algorithm, transmits data which don"t generate collision and must satisfy instruction code. So, to prevent data collision, transponder is of great if it read the entire instruction code. Consequently, it is applied to algorithm that made the system of wireless recognition 13.56Mhz. As a result, for the time of one bit data transmission had 14㎲ difference, it is proved the prevention of data loss in experiment.
