Remote readable ID tags are interest for their uses in various fields. In previous papers the author proposed the application of a new ID tag a s an intelligent pile in a location-detection system. This ID tag consists of a magnetic tape encoded by the magnetic head, a magnetostrictive strip that resonates at predetermined frequencies according to the encoded pattern for identification, and a housing for both of these components. Examination of the characteristics of this ID tag, especially as regards the capacity and the reading range, showed that encoding with a magnetic pattern is effective for both sinusoidal and rectangular patterns. A reading distance of about 60 cm was sufficient for identifying several patterns, and a distance of about 50 cm for was sufficient 20 bits, which can be obtained by using multiple strips. The operation temperature is from -20°C to 60°C.
