Near Field Communication (NFC) is a short-range contactless communication standard recently emerging as cashless payment technology. However, NFC has been proved vulnerable to several threats, such as eavesdropping, data modification, and relay attacks. A relay attack forwards the entire wireless communication, thus communicating over larger distances. In this paper, we review and discuss feasi...

In a number of different applications for enzymes and specific binding proteins a key technology is the immobilization of these proteins to different types of supports. In this work we describe a concept for protein immobilization that is based on nanofibrillated cellulose (NFC). NFC is a form of cellulose where fibers have been disintegrated into fibrils that are only a few nanometers in diame...

This study evaluated prototype multichannel nonlinear frequency compression (NFC) signal processing on listeners with high-frequency hearing loss. This signal processor applies NFC above a cut-off frequency. The participants were hearing-impaired adults (13) and children (11) with sloping, high-frequency hearing loss. Multiple outcome measures were repeated using a modified withdrawal design. T...

This work investigates the surface and bulk properties of nanofibrillated cellulose (NFC) and bacterial cellulose (BC), as well as their reinforcing ability in polymer nanocomposites. BC possesses higher critical surface tension of 57 mN m(-1) compared to NFC (41 mN m(-1)). The thermal degradation temperature in both nitrogen and air atmosphere of BC was also found to be higher than that of NFC...

Problem statement: Near Field Communication (NFC) technology opens up exciting new usage scenarios for mobile devices based platform. Users of NFC-enabled devices can simply point or touch their devices to other NFC-enabled elements in the environment to communicate with them (‘contactless’), making application and data usage easy and convenient. Approach: The study describes the characteristic...

Near Field Communication (NFC) technology is based on a short range radio communication channel which enables users to exchange data between devices. With NFC technology, mobile services establish a contactless transaction system to make the payment methods easier for people. Although NFC mobile services have great potential for growth, they have raised several issues which have concerned the r...

Valuable chemical compounds can be produced from corn stalk in a biorefinery by means of the organosolv process. However, 41% of the corn stalk is cellulose, which is commonly used to produce bioethanol whose profitability is not high because of the cost of the process. The use of this cellulose to produce nanofibrillated cellulose (NFC) could improve the profitability of the process. NFC has g...

With the increasing popularity of Near field communication (NFC) in consumer-off-the-shelf devices, more and more applications are taking advantage of the technology in innovative ways. Unfortunately, with the rise of NFC applications, there emerges a variety of vulnerabilities that could leave an unwitting user vulnerable to a data breach. One such potentially devastating attack is mobile pick...

Organisations want nowadays more controlled processes and easily usable solutions, but achieving them requires winning many challenges. Radio Frequency Identification (RFID) based technology has been proposed for improving mobile solution workflows and usability. NFC (Near Field Communication) technology is based on integrating RFID on mobile devices. This paper identifies how NFC based systems...

Near-field Communication (NFC) technology finally is starts to proliferate on modern smartphones, enabling researchers to conduct research in the large in the real world. The research question for this work is to learn about the distribution of NFC tags in the wild. As there is, for good and for bad, no central registry or database of NFC tags, we propose a gamebased approach to capture the ado...
