关键词： RFID   卷烟防伪   NFC   专卖管理  

摘要： 目前卷烟防伪主要采用的是激光全息、特殊油墨、特殊纸张、微缩印刷、电话短信查询、二维码查询等防伪技术。在巨大利益的驱使下,卷烟制假分子逐渐形成专业化、网络化的制假生产模式,主流防伪技术被一一突破,畅销品牌卷烟被制假者仿造得真假难辨。如何提升防伪技术水平,有效地进行品牌保护,切实地维护国家利益、维护消费者利益成为当务之急。因此我们有必要引进一种新技术,建设一套完善的产品防伪、溯源系统,提高烟草行业的整体防伪水平。本文就RFID技术在卷烟防伪领域的应用进行了可行性分析。

关键词： RFID   tracking   orientation   polarization  

摘要： RFID tracking attracts a lot of research efforts in recent years. Most of the existing approaches, however, adopt an orientation-oblivious model. When tracking a target whose orientation changes, those approaches suffer from serious accuracy degradation. In order to achieve target tracking with pervasive applicability in various scenarios, in this article, we propose OmniTrack, an orientation-aware RFID tracking approach. Our study presents a generic model that discribes the linear relationship between the tag orientation and the phase change of the backscattered signals. Based on this finding, we propose an orientation-aware phase model to explicitly quantify the respective impact of the read-tag distance and the tag's orientation. OmniTrack addresses practical challenges in tracking the location and orientation of a mobile tag. Our experimental results demonstrate that OmniTrack achieves centimeter-level location accuracy and has significant advantages in tracking targets with varing orientations, compared to the state-of-the-art approaches.

关键词： Accident dosimetry   RFID chip   OSL   SAR protocol  

摘要： OSL dosimetric studies have been carried out on wired chip card modules from employee identity cards (ID cards) from a premier government research institution. The OSL dose response of chip card modules shows a linear behavior upto a dose of 20 Gy and thereafter exhibited a sub-linearity. The homogeneity of OSL signal among different cards as well as the repeatability studies were carried out and were found to be satisfying the requirements of IEC. The signal was found to be stable after 4 days of storage. In addition, dose recovery methodology was suggested for RFID chip card module and the same has been validated with different chip card modules.

关键词： Chipless RFID   Embroidered tag   Circuit modelling   Transient response   Radar cross section   IoT applications  

摘要： This paper presents the design, fabrication and testing of two embroidered chipless octagonal-shaped RFID tags on cotton fabric for wearable applications. The first tag is designed by using silver-coated polyamide conductive fibre (HC12) and the second tag is embroidered by using highly conductive Vectran (LIBERATOR 40) which is highly conductive multifilament yarn spun from Liquid Crystal Polymers (LCP), on cotton fabrics. In contrast to the traditional RFID tag, the chipless RFID tagging, the ID code is not saved in the memory, instead, it uses the physical features of the tag to send data. The proposed tag's design uses a Frequency Selective Surface (FSS) technique for the frequency range of 8-18 GHz. These tags are designed using CST studio and precisely fabricated by using commercial ZSK Technical Embroidery System JCZA (0109-550). The tag design is composed of six concentric octagonal loop resonators with one unitary element. The electromagnetic scattering waves behaviour and Singularity Expansion Method (SEM) based circuit modelling for the octagonal-shaped tag is performed, and the coupling coefficients are evaluated. The desired data bits are obtained by a series of comparative experiments for Radar Cross Section (RCS) in an anechoic chamber. The experimental results obtained show that the 4-bit data is accurately retrieved with the variation of distance by up to 1.8 m at 0 dB m. Moreover, the average transition from minimum '0' to maximum 1' is -27 dB for both designs. Furthermore, the experimental results for on-body RCS measurements and the bending effects on both tags down to 7 mm is observed. This octagonal embroidered Chipless RFID tag is a fully textile design which is compact and can be deployed commercially in various IoT applications. (C) 2020 Elsevier B.V. All rights reserved.
