The paper presents the results of laboratory tests of passive RFID tags, which were conducted at the laboratory in order to determine the application area of this technology. The study was conducted in three stages: transponders reviews, that involved reading parameters such as the positional relationship between the transponder antenna and the maximum reading distance. The influence of typical packaging materials such as cardboard, foil, etc. on the correctness of reading was also taken into account, dynamic tests of transponders that involved reading tags in a linear or rotary motion at diff erent speeds. Reading more moving transponders, which are also close to each other, was carried out, and transponders research programme, which was to determine the possibility of writing such information and programming during movement.
