Mobile wallets promise to allow people to easily manage their accounts and to carry less cards. However, the slow adoption of contactless point of sales (POS) terminals by merchants limits the potential of Near-Field Communication (NFC) based payment devices. In this paper, we discuss Wild Card, a secure and backward compatible way to make mobile payment through conventional magnetic stripe bas...

The integration of Near Field Communication (NFC) into consumer electronics devices has opened up opportunities for the internet of things applications such as electronic payment, electronic ticketing and sharing contacts, etc.. Meanwhile, various security risks should not be ignored. Therefore, all kinds of different protocols have been released with the purposing of securing NFC communication...

Software card emulation is a new approch to advance the interoperability of NFC with legacy contactless smartcard systems. It has been first introduced to NFC-enabled mobile phones by Research In Motion (RIM) on their BlackBerry platform. Software card emulation aims at opening and simplifying the complex and tightly controlled card emulation functionality. While this form of card emulation, th...

Following students’ attendance is a challenging and time-taking process for the instructor. At colleges, attendance is taken by passing around the attendance list which the students sign and write their ID numbers. This decreases the efficiency of the course and causes time loss. Taking university students’ attendance is an important activity for instructors and student alike and for increasing...

To move electrochemical sensing technology from the laboratory into point-of-care (POC)-based settings, platforms must be cost-effective, portable, and user-friendly. Here, we present comparison of a near-field communication (NFC) potentiostat with traditional potentiostat. The NFC is roughly size credit card wirelessly powered by smartphone user-friendly application for analysis.

A novel method for the preparation of composites based on poly(vinyl alcohol) (PVA) and microand nano-fibrillated cellulose (M/NFC) is reported. The addition of crosslinking HEMA monomers and a photo-initiator enabled the formation of an interpenetrated polymer network that displayed enhanced interfacial adhesion and dispersion of (M/ NFC) in the matrix. Photo-crosslinked PVA/(M/ NFC)/polyHEMA ...

Cellulose-based materials are widely used in a number of important applications (e.g. paper, wood, textiles). Additional developments are suggested by the growing interest for natural fibre-based composite and nanocomposite materials. The motivation is not only in the economic and ecological benefits, but is also related to advantageous properties and characteristics. The objective of this thes...

article entitled 'Comparison of laser Doppler imaging, fi ngertip lacticemy test, and nailfold capillaroscopy for assess ment of digital microcirculation in systemic sclerosis' [2], which was published in a recent issue of Arthritis Research & Th erapy. Sulli and colleagues commented on our results regarding the lack of correlation between the laser Doppler imaging (LDI) technique and nailfold ...

Background: Microvascular changes are one of the first obvious steps in numerous inflammatory diseases such as rheumatoid arthritis (RA). Nailfold video capillaroscopy (NFC) is an easy, reliable and safe method for evaluating peripheral microangiopathy. The objective of this study was to examine nailfold microcirculation in RA patients, assess morphological and structural changes quantitatively...

This paper gives bird’s-eye view of a variety of wireless access systems with respect to communication protocol structure. As these technologies evolve to higher datatransmission rates, there is more affinity with the Internet protocols. This observation motivates discussions of wireless access convergence in the future. For instance, communication protocols for IC-cards and RFIDs, which are qu...
