Many wireless technologies are used to establish the communication between tags and readers. Most popular ones include WiFi, GPS, Infrared, Bluetooth, and active and passive RFID systems. Table 1 summarizes the differences of these technologies, their prominent features, and the performance that determine their suitability to different applications. There is no “one size fits all” solution when...

With recent advances in wireless technologies, RFID (Radio Frequency Identification) becomes an important enabling technology for logistics and supply chain management systems and beyond. Effective deployment of these systems requires careful selection and seamless integration of RFID components such as tags, readers, middleware and standards. The frequent releases of new RFID components obsole...

This paper introduces a small-size, low-profile wearable radiator based on the coupled patches and vertically folded patches techniques for application as a tag antenna for identification of people in the European UHF RFID band. The electric field distribution comes out dominantly from the central coupling slot, and thus the electric properties of the radiator are almost unaffected by the human...

The 2.4 GHz frequency band is available throughout most parts of the world for low cost short-range wireless communications and has increased in popularity with the proliferation of networking and cordless technologies based on IEEE 802.11 and Bluetooth. A growing number of RFID systems have also been designed for operation within the 2.4 GHz ISM frequency bands. As more wireless technologies s...

The paper proposes and discusses the integration of WSN and RFID technologies in the IoT scenario. The proposed approach is based on the REST paradigm, thanks to which the two technologies can be seamless integrated by representing sensors, actuators and RFID related data as network resources globally addressable through state-of-the-art IoT protocols. The integration approach is detailed for t...

Due to increasing concerns about environmental protection, the environmental sustainability of businesses has been widely considered in the manufacturing and supply chain context. Further, its adoption has been implemented in the retail industry for marketing field, including green product promotion. This study aimed to propose a customer purchasing behavior analysis as an alternative for suppo...

Novel eagle shape microstrip wearable antennas (element and array) are presented. The singleand two-element antenna arrays are designed and fabricated on a Roger RT/Duroid 5880 substrate with dielectric constant of 2.2, thickness of 1.5748mm, and tan δ = 0.001. The measured results show that a reduction in mutual coupling of 36 dB is achieved at the first band (1.68–2.65) GHz and 22.1 dB over t...

The tagging of objects or people with devices containing some form of unique ID that can be read remotely is a valuable technique for wearable computing applications. Many technologies have been adopted to support this functionality ranging from RFID tags to printed QR codes. In this demo we present an ultrasonic tag design with a range of over 8 metres which can be implemented using low power ...

An essential factor adversely affecting the performance of construction projects is the improper handling of materials during site activities. In addition, paper-based reports are mostly used to record and exchange information related to the material components within the supply chain, which is problematic and inefficient. Generally, technologies (such as wireless systems and RFID) are not bein...

Radio Frequency Identification (RFID) and Wireless Sensor Network (WSN) are two important wireless technologies that have wide variety of applications and provide limitless future potentials. However, RFID and sensor networks almost are under development in parallel way. Integration of RFID and wireless sensor networks attracts little attention from research community. This paper first presents...
