of providing services that is now perceived as traditional one is the most acceptable for them. It is established that the leader in the use of online services is a taxi. This service is used by all students to some extent, followed by the service of food delivery and only then online banking, online shopping and public services. The novelty and originality of the study lies in the fact that the features of consumption practices among students actively practicing online services and avoiding them are revealed. It is established that students who have little recourse to online services are wary of modern services, which is based either on the previous negative experience of use, or on the unsatisfactory experience of friends, believe that those techniques and applications that are now on the market are not optimal for them and the usual methods of obtaining services for them remain more comfortable and familiar, even though more time spent on obtaining a particular service. The practical significance lies in the fact that the data obtained in the work can be used in social psychology, age psychology, labor psychology, management, sociology, as well as for further theoretical development of this issue.
Radio frequency identification (RFID) is a widely used wireless technology for contactless data exchange. Owing to international standardization and one-way security nature of the communication protocol, RFID tags, holding sensitive information, may be a subject to theft. One of the major security loopholes is the so-called far-field attack, where unauthorized interrogation is performed from a distance, bypassing the user’s verification. This loophole is a penalty of using a dipole-like RFID tag antenna, leaking wireless information to the far-field. Here we introduce a new concept of anapole-enabled security, prohibiting far-field attacks by utilizing fundamental laws of physics. Our design is based on radiationless electromagnetic states (anapoles), which have high near-field concentration and theoretically nulling far-field scattering. The first property enables performing data readout from several centimeters (near-field), while the second prevents attacks from a distance, regardless an eavesdropper’s radiated power and antenna gain. Our realization is based on a compact 3 cm high-index ceramic core–shell structure, functionalized with a thin metal wire and an integrated circuit to control the tag. Switching scheme was designed to provide a modulation between two radiation-less anapole states, blocking both up and down links for a far-field access. The anapole tag demonstrates more than 20 dB suppression of far-field interrogation distance in respect with a standard commercial tag, while keeping the near-field performance at the same level. The proposed concept might significantly enhance the RFID communication channel in cases, where information security prevails over cost constrains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
