Thesis The use of RFID technology in retail systems focuses on the advantages of RFID technology through a review of many examples of RFID technology applications in various industrial, economic and technological fields. Unfortunately, due to the long period of return of investment in RFID, it is rarely used in retail systems. Therefore, special attention is dedicated to the project task where data collected through the model of RFID system emphasize the advantages of implementing the RFID system in the retail system. By analyzing and comparing the results obtained from model with the actual data collected in the standard retail system used by the barcode labeling we came to detailed data as evidence of the benefits of the RFID system. The billing process is broken down into the elements, and a comparison of data is performed at the level of each element to obtain the most accurate differences in the individual phases of the billing process. Result of the model and data analysis is a very detailed picture of the benefits of the RFID system and the disadvantages of the existing retail systems. Data is compared at each element of the billing process in order to obtain as much granulation of results as possible to highlight the benefits of the RFID system in each activity of the billing process while simultaneously highlighting the disadvantages of existing retail billing systems where a barcode labeling product is used.
