AbstractThis paper proposes a visual management scheme of medical things with a color-change radio frequency identification (RFID) tag. The color-change RFID tag employs a specific RFID tag integrated circuit (IC) and a laminated pH-indicating paper. The IC has energy harvesting and switched ground functions, which enable it to generate electricity to the laminated pH-indicating paper. This phenomenon causes electrolysis of NaCl solution absorbed in the laminated pH-indicating paper. Electrolysis generates alkaline matter to change the color of the pH-indicating paper. This paper gives a new and sensitive structure of the laminated pH-indicating paper. The proposed advanced color-change RFID tag with new laminated pH-indicating paper succeeds in changing its color noticeably at a 1 m distance using an RFID reader radiating 1 W radio waves. The color change was observed 3–5 s after starting radio wave irradiation. The results of this experiment also confirm that the changed color can be held for over 24 h. Furthermore, two demonstrations of the visual management system of medical things (patient clothes and sanitizers) are presented.

This study represents a device to identify the location of an Autism Spectrum Disorder(ASD) child using an Radio Frequency Identification (RFID). This is a wearable device, that is to be worn by the autism child, which allows the parent to track the child anytime, anywhere .The RFID technology is implied for the location tracking, The RFID Tag is affixed on the device, the reader which is supposed to sense the RFID tag is placed at the spots such as classroom etc. The reader when it senses the tag notifies the parent through a message. When an RFID tag passes through the electromagnetic zone, it detects the activation signal produced by the reader. The encoded data present in the integrated circuit of the tag is being encoded by the reader and the data is delivered to the host computer for processing. The location can be sent to parent in the form of a normal text message via GSM. Autism children deserve to acquire knowledge and explore the environment. To overcome the obstruction this device will be of immense help.

Frequency Identification

Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity of an object or person wirelessly using radio waves (RFID Journal, 2005). It falls under the broad category of automatic identification technologies. RFID tags, in the simplest of terms, are “intelligent chips that can be embedded in or attached to a product to transmit descriptive data” (Gelinas, Sutton, & Fedorowicz, 2004, p. 6). According to the online RFID Journal (2005), there are several methods of identifying objects using RFID, including the most common of storing a serial number that identifies a product on a microchip that is attached to an RFID tag. RFID is not a new technology, but it has only recently been in the spotlight as more businesses are receiving press for putting the technology to work in their supply chains. RFID tag technology is sometimes associated with the term electronic product code (EPC). An EPC uniquely identifies objects in a supply chain. According to EPCGlobal, “EPC is divided into numbers that identify the manufacturer and product type. The EPC uses an extra set of digits, a serial number, to identify unique items.” The EPC number is placed on a tag composed of a silicon chip and an antenna, which is then attached to an item. Using RFID, a tag communicates its numberto a reader (EPCGlobal, 2005). In broad terms, RFID tags are placed into one of two categories: active or passive. According to the Association for Automatic Identification and Mobility (AIM, 2005), active RFID tags are powered by an internal battery and are typically designated as read-write tags. When a tag has read-write capabilities, the tag data can be modified. Passive tags, according to AIM, operate without a power source and obtain operating power from the tag reader. Passive tags are typically read-only tags, having only read-only memory. Active tags generally have a longer read range than passive tags.

Abstract 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.

The electromagnetic (EM) imaging technique at mm-band 60 GHz is proposed for data encoding purpose in the chipless Radio Frequency Identification (RFID) systems. The fully printable chipless RFID tag comprises tiny conductive EM polarizers to create high cross-polar radar cross-section. Synthetic aperture radar approach is applied for formation of the tag's EM-image and revealing the tag's content. The achieved high data encoding capacity of 2 bits/cm2in this technique based on a fully printable tag is very convincing for many applications. The system immunity to multipath interference, bending effect, and printing inaccuracy suggests huge potentials for low-cost item tagging. Tags are also readable through a tick paper envelop; hence secure identification is provided by the proposed technique.

Abstract This paper presents a polarization-independent 11-bit chipless RFID tag based on frequency-selective surface which has been designed for encoding and relative humidity (RH) sensing applications. The 10 exterior U-shaped resonators are used for item encoding whereas Kapton has been incorporated with the interior resonator for RH sensing. This radio-frequency identification (RFID) tag operates in S- and C-frequency bands. The proposed design offers enhanced fractional bandwidth up to 88% with the density of 4.46 bits/cm2. Both single- and dual-layer tags have been investigated. The simulated results are in good agreement with measured results and a comparison with existing literature is presented to show the performance. Simple geometry, high code density, large frequency signature bandwidth, high magnitude bit, high radar cross-section, and angular stability for more than 75° are the unique outcomes of the proposed design. In addition, RH sensing has been achieved by integrating the Kapton on the same RFID tag.
