The dissertation deals with the potential of radiofrequency identification in the safety field. The thesis describes the analysis and verification of the possibilities of RFID application in two application cases – identification of protective suits and short firearms. In the introductory part are the possibilities of RFID described, description is focused mainly on the UHF band components. Following the analytical part I carry out suggestions on the use of specific hardware. I compare and verify the features of selected devices via laboratory and in situ experiments, a matter of course is a statistical evaluation of the experimental results. For protective suits management system resistance to temperatures, liquids and washing process are essential. Software processing data from RFID technology was designed as well. Similarly, I have also explored the possibility of application of this technology in the area of firearms management systems, where the most important limit is the applicability to metal surfaces along with minimization of ergonomics disruption.

The dissertation discusses the possibilities of radio frequency identification technology for identification of movement of objects in defined space. The initial impetus for starting research in this area came from the business chain in private sector. Because of this the dissertation is focused primarily on tracking movement of customers within shopping area. The first chapters deal with RFID technology in general and its use in the business chains environment. The following chapters describe the application of theoretical RFID knowledge into practice, draft and preparation of technical solutions enabling tracking of objects in defined space. The dissertation then moves on from laboratory tests to experiments in real environment of a business chain, their practical verification, analysis and evaluation. The experiments at the end of the dissertation confirm feasibility and transfer of acquired knowledge into the environment of raw materials industry company engaged in coal mining.

The technologies of automatic identification are beginning to apply more and more. They allow proving technological processes and observing the rules in various productions. The advantage of RFID technology is the fact that there is not necessary direct visibility for reading; it is also interesting to read multiple RFID tags simultaneously compared to other possibilities of identification. Another advantage of RFID tags is the ability to withstand higher temperatures, humidity and environmental effects in general. It has the big meaning to observe hygienic regulations in food industry.

Dissertation deals with research and design of automatic identification using based on RFID technology in logistic-production process in Nestlé company. The attention is focused on applying of suitable HF and UHF RFID tags for needs of automatic identification of the original food moulds. Suitable RFID tag will be chosen based on the testing. It will have to meet the specified requirements for automatic identification needs of moulds which are used in specific operating conditions.

Selection of the appropriate frequency is one of the most important and the first design phases of automatic identification solutions based on RFID technology. A number of other restrictions follow from this choice, such as reader range, speed of reading and writing, applicability in different environments and more.
