Abstract :
Identification by use of radio frequencies provides a tool for physical identification of objects, without the need to be checked with human eyes. The most effective factors in these systems are tags, readers, and the environment of the operation. Mounting devices for the tags have a direct effect on the efficiency of tag operation, especially near water and metal. The goal of this article is to introduce a set of experiments for checking the quality of tags in such systems. To achieve this goal, doing experiments of the maximum distance between tag and reader that be possible to read the tag; and sensitivity to orientation and also the efficiency of tags near materials in the UHF band for evaluating and comparing the operation of tags is necessary and therefore tag's operation will be investigated in three environments: free, tag near water and metal.
