RFID tags have been used by railways for many years, RFID has proven its worth in inventory management, yet this technology is underutilized for enhancing railway operations and health monitoring due to limitations of passive RFID technology. Active RFID provides enhanced capabilities with potential to improve railway operations. Active technology differs from passive RFID by incorporating an onboard power source enabling longer ranges, changeable data fields, and the ability to transmit independently of the reader. This paper compares the advantages and disadvantages of active compared to passive RFID in terms of power requirements, transmission range, and dynamic data. A survey of existing products and vendors is presented. The existing active RFID standards are reviewed and elements of the data tag protocols are detailed as well as protocols for mitigating collisions of data packets. Finally, specific railway applications utilizing active RFID are discussed.

RFID technology has been widely used in mobile robot positioning system for its unique advantages. RFID tags store their unique positions which are placed on the ceiling or the floor. The mobile robot carries a RFID reader which reads the RFID tags to position itself. In this paper, a new method for mobile robot localization is proposed, and the equations to calculate the position of the mobile robot are given. Finally, the experiment results show that compared to conventional positioning method, the proposed method can effectively improve the positioning accuracy of the mobile robot.

The purpose of the research is to study the benefits and potential problems of using Radio Frequency Identification Devices (RFID) in the warehouse management and inventory supplychain management. Methodology. In the process of writing this article a few various types of the observation, timing, motional, inventory, and historical methods (describing present time limitations of the current inventory tracking system compare to the benefits and obstacles of the proposed new generation inventory management system) were used. To support our conclusion, we used data from the sampling research conducting on the premises of six distribution centers. Generalized results of this study helped us to create a comparison between deployment of the system with the use of just RFID tags, just barcodes, and a hybrid technology, were both types of the inventory markings were incorporated. Results. As it was predicted even before the research begins, the result of the study proved that use of the RFID technology significantly improved reliability of the inventory system by reducing number of out-ofstock (OOS) items, improved speed of the data collection and reduce amount and time of the manual work. It was also determined that RFID technology will help companies to better manage day-to-day inventory operations. The overall results suggested that use of the RFID technology will help companies to reduce fixed and variable costs associated with the daily operation of the inventory management system. However, it was also found that RFID system is not prone to the problems related to the breakage of the equipment and tags themselves. It is also worth to take into account a cost of RFID tags compares to the barcodes or two-dimensional barcodes. If a medium size company will decide to switch to the RFID technology completely, the cost of the switch might not overweight the saving the company will have. In this case a possible solution might be two-dimensional barcodes. Practical meaning. We hope that results of the study, our observations, and comments will help businesses to evaluate deployment of the RFID technology better, understand some unrecognized pro and cons of it and find possible ways to improve on the current systems by using advantages of multiple inventory solutions. Prospects for further research. Consideration should be given to a possible research of the security of the RFID technology, safety of the protocols it uses to collect and transmit data, and, finally, a possibility of the external intrusion and malicious data manipulations and the ways to prevent it.

In this paper, a review of the state-of-the-art chipless radiofrequency identification (RFID) technology is carried out. This recent technology may provide low cost tags as long as these tags are not equipped with application specific integrated circuits (ASICs). Nevertheless, chipless-RFID presents a series of technological challenges that have been addressed by different research groups in the last decade. One of these challenges is to increase the data storage capacity of tags, in order to be competitive with optical barcodes, or even with chip-based RFID tags. Thus, the main aim of this paper is to properly clarify the advantages and disadvantages of chipless-RFID technology. Moreover, since the coding information is an important aspect in such technology, the different coding techniques, as well as the main figures of merit used to compare different chipless-RFID tags, will be analyzed.

This paper introduces an anti-theft detection system for public bicycles, which can work in ways of both passive RFID and active RFID. The overall systematic framework is analyzed, and the circuits for microcontroller for RFID and RF front-end in the system are focused on. The anti-theft software process in the project implementation is also presented. We have done the design of RFID, including the software and hardware. After debugging, the RFID operates well. The RFID had done well in reducing traffic pressure in Hangzhou, Jiangyin and the other cities.

This article discusses the topic of labeling postal shipments by passive radio frequency identification (RFID) tags. Every delivery company needs to have all necessary information for every single postal shipment package it carries. Shipment package labeling is essential for processing and tracking the postal shipments along its delivery process. Using RFID technology for the process brings advantages in more efficient delivery and data collection along with regular information updates of shipment status across complete delivery chain.In this article, we focused on the problem of logical log of key shipment package information into EPC memory of the RFID smart label. We have taken into account the National postal administrator and its current system of shipment labeling. In the end, we presented a design for conversion of contemporary labeling using bar codes into labeling using RFID tags.

This paper presents a system with location functionalities for the inventory of traffic signs based on passive RFID technology. The proposed system simplifies the current video-based techniques, whose requirements regarding visibility are difficult to meet in some scenarios, such as dense urban areas. In addition, the system can be easily extended to consider any other street facilities, such as dumpsters or traffic lights. Furthermore, the system can perform the inventory process at night and at a vehicle’s usual speed, thus avoiding interfering with the normal traffic flow of the road. Moreover, the proposed system exploits the benefits of the passive RFID technologies over active RFID, which are typically employed on inventory and vehicular routing applications. Since the performance of passive RFID is not obvious for the required distance ranges on these in-motion scenarios, this paper, as its main contribution, addresses the problem in two different ways, on the one hand theoretically, presenting a radio wave propagation model at theoretical and simulation level for these scenarios; and on the other hand experimentally, comparing passive and active RFID alternatives regarding costs, power consumption, distance ranges, collision problems, and ease of reconfiguration. Finally, the performance of the proposed on-board system is experimentally validated, testing its capabilities for inventory purposes.

Over the past decade, electromagnetic and communication science societies, along with improving the classical RFID technology, have put in a great deal of effort in designing novel and more complex UHF RFID tags with augmented capabilities. Novel tags offer additional functionalities besides identification by embedding sensors, actuators, and processing units. In this work an enhanced version of one of such devices, called SPARTACUS, is presented. While being completely passive, it conjugates identification, sensing, local computing, and actuation control and enables a proactive communication with any standard RFID reader. The paper presents details on a novel logical communication procedure over Low Level Reader Protocol (LLRP), besides discussing system validation and performance evaluation.
