Special Issue Information

Dear Colleagues,

In the last decade, radio frequency identification technologies have arisen as a vital enabler for countless applications beyond logistics. Environmental sensing, healthcare utilization, automation, and localization are just a few applications that benefit from the latest research on RFID devices and systems. Fostered by the progress in fabrication and an increasingly common diffusion well beyond academic settings, research on these devices has surged in recent years so that an even more extensive and variegated adoption can be envisioned in the near future. Nowadays, the state of the art of RFIDs draws from the achievements in a vast portion of the scientific knowledge that spans from communication protocols to material science. Furthermore, it is expected to be revitalized by the diffusion of wireless communications beyond fifth generation (5G+).

As the literature on this topic increases wildly, like the number of practitioners pushed by the vision of the Internet of Things, this Special Issue aims at collecting diverse works regarding the plethora of different aspects of the flourishing radio frequency identification in the same place. Given that the scope is broad and heavily multidisciplinary, the purpose of this Special Issue is also to cover the advances in related research that are easily translated into the RFID domain, such as microwave research in the RFID frequency band and manufacturing techniques for antennas. Our intention is for the Special Issue to highlight the diversity of the research lines currently in practice through specific works to help identify new and undiscovered research questions and establish novel collaborations between the extensive scientific community interested in RFIDs. Both original research and review papers are welcome!

Topics of interest may include, but are not limited to, the following:

  • RFID systems and devices;
  • NFC applications and protocols;
  • Wireless power transfer and energy harvesting;
  • Microwave technologies at RFID frequencies;
  • Manufacturing and fabrication techniques;
  • Algorithms exploiting data collected through RFID;
  • Security of RFID devices and communications;
  • Advances in chipless technology;
  • Industrial usage of RFID;
  • Antennas for RFID;
  • Computational RFID;
  • Wearable and biomedical applications.

RFID-based technology innovated a new field of wireless sensing, which has been applied in posture recognition, object localization, and the other sensing fields. Due to the presence of a Fresnel zone around a magnetic field when the RFID-based system is working, the signal undergoes significant changes when an object moves through two or more different Fresnel zones. Therefore, the moving object can be sensed more easily, and most of the sensing applications required the tag to be attached to the moving object for better sensing, significantly limiting their applications. The existing technologies to detect static objects in agricultural settings are mainly based on X-ray or high-power radar, which are costly and bulky, making them difficult to deploy on a large scale. It is a challenging task to sense a static target without a tag attached in NLOS (non-line-of-sight) detection with low cost. We utilized RFID technologies to sense the static foreign objects in agricultural products, and take metal, rock, rubber, and clod as sensing targets that are common in agriculture. By deploying tag matrices to create a sensing region, we observed the signal variations before and after the appearance of the targets in this sensing region, and determined the targets’ positions and their types. Here, we buried the targets in the media of seedless cotton and wheat, and detected them using a non-contact method. Research has illustrated that, by deploying appropriate tag matrices and adjusting the angle of a single RFID antenna, the matrices’ signals are sensitive to the static targets’ positions and their properties, i.e., matrices’ signals vary with different targets and their positions. Specifically, we achieved a 100% success rate in locating metallic targets, while the success rate for clods was the lowest at 86%. We achieved a 100% recognition rate for the types of all the four objects. Full article

The intensive development of information and telecommunications technology has a very large impact on society. On the one hand, it greatly facilitates many activities in everyday life, such as searching for information, establishing contacts with other people, or controlling household appliances at a distance. On the other hand, it poses serious threats to our personal data, the information we process, or our property. One of the examples of such threats may be radio identification systems, enabling the registration of working time, entry into restricted zones in workplaces and offices, or warehouse data. Copying data from an identification card may allow unauthorized persons access to premises and data that they should not have. The article presents the principles of operation, the results of the conducted research, and their analysis in the aspect of security of the short-range radio frequency identification systems used in relation to the RFID 125 kHz system, broadly used in access control systems or time and attendance systems. Particular attention has been paid to the possibility of unauthorized acquisition of information contained in the identification card in order to, for example, copy it and gain access to specific protected zones. An analysis of the security of such systems was carried out not only in relation to the data carriers themselves but also to complete access control systems installed in buildings. The research focused especially on the ability to determine the range of information penetration, i.e., the distance of remote information acquisition using electromagnetic radiated emissions.

Passive radio frequency identification (RFID) tags have been widely used in logistics, supply chain, warehousing, and other fields. However, for RFID-based automatic inventory management in warehouses, the deployment of current methods is more complex, and the localization range still has some limitations. This paper proposes DNCL, which is a hybrid passive RFID localization scheme based on direction-of-arrival (DOA) estimation and nonmetric multidimensional scaling (NMDS) to achieve spatial coordinate localization of tagged objects on shelves or racks using a single antenna for simple 1D scanning. DNCL uses antenna dynamic scanning to generate a virtual antenna array for the dynamic information capture of tags in the scene, which helps eliminate the phase shift produced by ambient noise. We apply the angle profile linear model to identify the characteristics of each tag and introduce the NMDS algorithm to improve the robustness of the scheme through the fixed layout of the reference tags, which can reliably estimate the coordinates of the tagged objects in the space. This paper realizes a prototype system and validated its practical performance in real complex situationse by COTS RFID devices. The results indicate that DNCL can achieve high accuracy for the localization of passive tags in free space. Full article
