The reason of this question is to find the project purpose and design. Basically, it's about two basic tasks: identification and localization. The identification consist in reading of the unique identifier that is assigned to a particular tag. The localization requires to determine where the tag is identified, i.e. the coordinates where the identification tag was read. For identificarion it is sufficient to use mostly the passive tag technology with peer-to-peer communications with one reader. For localization must be used the active tags and a readers network.

The reason of this question is to find the properties of the subject of the identification or localization. Each of the materials has an impact on the reading distance, certain materials have enabled and certified only one frequency. Lower frequencies are more resistant to jamming and influences around, but have porter reading distance. The higher the frequency, the higher the reading distance, but even greater interaction with the surroundings. For metallic materials, which significantly affect the reading characteristics it is necessary in all cases to provide either greater space between the tag and the lush material, or use a special tag that uses a metal substrate such as reflective surface for the antenna.

The reason of this question is to determine the conditions under which the process of data exchange between tag and reader takes place. In addition to the physical limitations of the transmission speed of reading and writing, which in practice have the effect, in particular on the identification of high-speed processes on printing machines, is for system settings necessary to determine, how the individual elements are moving relatively to each other.

The reason of this question is the detection of physical conditions of reading. RFID tags are mostly made up of non-electronics for which the standard conditions of functionality in terms of temperature, humidity and electromagnetic interference are valid. Basic electronics of a tag is functional in a temperature range between -36°C to 65°C and there has to be thermal insulation if there is a need to increase this range.

The reason of this question is the detection of typical required properties of the RFID tag. By default, they are manufactured with 96 bit memory which is sufficient to write the 12 characters from the ASCII table. These tags are therefore inappropriate to write the information other than the unique ID. Other information must be available in the database. Atypical tags can be equipped with additional user memory suitable even for writing other data. In addition to its own memory it is possible to equip RFID tags with sensors that capture the physical conditions of the surrounding environment. These tags are produced in both passive and active implementation.
