An essential part of an electric energy service is an electrical power meter. Numerous customers have already expressed dissatisfaction over the electric meter's faulty readings. The development of an electrical power meter with an NFC reader is presented in this study. When an NFC card is successfully scanned by the NFC reader, the power meter is turned on and ready to deliver electricity. Before the electricity is automatically turned off, or when the credit is almost low, the display will show the alert. By experiment, PZEM 004T sensor use 3 loads, namely 60 W, 75 W and 100 W for testing current, voltage and cos phi and have error of 0 – 1.20%. In balance reduction with loads of 60 W, 75 W, and 100 W with a time gap of 5 and 10 minutes, there is an error reduction of 11.5 – 17.4%. Thus, this electricity meter with NFC reader is suitable for monitoring and controlling electricity usage.

Aplikasi Kehadiran Mahasiswa Menggunakan NFC Card Berbasis Mobile Android

Various kinds of activities in the fields of communication, information, transportation, banking, education, and those that require high mobility, require a supporting technology to do so. The supporting technology is a smartphone, where this smartphone is almost owned by every level of society. Smartphones are widely used in education to support learning between lecturers and students. At the University of Singaperbangsa Karawang Faculty of Computer Science, there is one aspect of student assessment that is measured based on the number of students pre-sent. The attendance system that runs at the Singaperbangsa University of Karawang, Faculty of Computer Science, has not yet implemented smartphone technology in its implementation. The problems that arise with the attendance system at this time is the presence data that has no backup if lost and absenteeism records that are easily damaged. Therefore the design and manufacture of the NFC Presence application is carried out to overcome this problem. The NFC Pres-ence application was built using the Mobile Application Development Life Cycle (MADLC) method. NFC (Near Field Communication) on smartphones and NFC Card is a tool to support student attendance data, which will then be stored properly in the database to prevent student attendance data loss. The attendance pro-cess in the NFC Presence application is done by mentoring an NFC card containing data in accordance with the data-base to the lecturer smartphone. Furthermore, the lecturer smartphone will send attendance data to the database, so that this data can be accessed anytime, anywhere.

WITHDRAWN: NFC based data monitoring and medication scheduling for patients in hospitals

Abstract Patient medication programming is crucial for successful day-to-day tracking in a health sector. It should be pointed out that a well-designed medication plan and data management system will help to access prescription care quickly and efficiently and to increase patient fulfilment. We normally have patient arrivals and registration formats filled out and we wait until the date and availability of the doctors have been settled upon. In the past, there have been some studies into the development of online and mobile appointment. Some have priority appointments.But there is still the wait and the pause in the exploration of a patient. In this regard a preceding updating and appointment system based on the Near Field Communication (NFC) has been established that enables patients to tap the NFC appointment chart at their reception or in their nurse pc or the doctor pc at their hospital/clinic for regular and emergency therapy. The system has a priority scheduling of medicinal items and NFC (RFID) card notification, which relies purely on nurses rather than on software with a message warning service using the Internet.

You Foot the Bill! Attacking NFC With Passive Relays

Imagine when you line up in a store, the person in front of you can make you pay her bill by using a passive wearable device that forces a scan of your credit card or mobile phones without your awareness. An important assumption of today's near-field communication (NFC)-enabled cards is the limited communication range between the commercial reader and the NFC cards. Previous approaches effectively used mobile phones and active relays to break the range limit of NFC propagation for the NFC attack. However, these approaches require a power supply and protocol modification when mobile phones or active relays transmit NFC signals. We propose ReCoil, a system that uses passive relays to attack NFC-enabled mobile phones or cards by expanding the communication range of NFC to 49.6 cm, an obvious improvement over its intended commercial distance. ReCoil is a magnetically coupled resonant wireless power transfer system, which optimizes the energy transfer by searching the optimal geometry parameters. Specifically, we first narrow down the feasible area reasonably and design the ReCoil-greedy algorithm such that the relays absorb the maximum energy from the reader. In order to reroute the signal to pass over the surface of the human body, we then design a half waistband by carefully analyzing the impact of the distance and orientation between two coils on the mutual inductance. Then, three more coils are added to the system to keep enlarging the communication range. Finally, extensive experiment results validate our analysis, showing that our passive relays consisting of common copper wires and tunable capacitors can expand the range of NFC to 49.6 centimeters.

83‐1: Enhancing the Performance of Display‐Integrated NFC Antenna by Magnetic Resonance Coupling for Secure Contactless Payment Transactions and for IOT

We propose a display‐integrated Near Field Communication (NFC) antenna design using Magnetic resonance coupling (MRC) for enhanced NFC power transfer and for extended large area NFC interface. By using MRC the power transfer, expressed in induced electric potential, from display‐integrated NFC antenna transmitter to the Proximity Integrated Circuit Card (PICC) tuned to 16.1MHz at height of 40 mm from the center of the integrated transmitter is enhanced to 2.93 V from 1.91 V, obtained without using MRC. MRC approach also allows expanding the NFC card readable area to farther than 2.5 times the size of the antenna. As a result, the power transfer characteristics of MRC based Display‐integrated NFC transmitter antenna are compatible with the Europay MasterCard Visa consortium (EMVCo) standard for contactless payments transactions and the design is suitable solution for large area NFC interface for connected devices in Internet of Things (IOT) applications.

User-friendly deniable storage for mobile devices

Mobile devices are prevalently used to process sensitive data, but traditional encryption may not work when an adversary is able to coerce the device owners to disclose the encryption keys. Plausibly Deniable Encryption (PDE) is thus designed to protect sensitive data against this powerful adversary. In this paper, we present MobiPluto, a user-friendly PDE scheme for denying the existence of sensitive data stored on mobile devices. A salient difference between MobiPluto and the existing PDE systems is that any block-based file systems can be deployed on top of it. To further improve usability and deniability of MobiPluto, we introduce a fast switching mechanism and incorporate the widely-used Near Field Communication (NFC) technology. Users can securely switch from the public mode to the hidden mode within 10 seconds, which is a significant improvement compared to previous solutions. Users can also store strong passwords on NFC cards and tap them to enter the system, which significantly liberates them from the burden of memorizing and typing strong passwords. Most importantly, the users can deny the existence of the hidden data without the skill to camouflage as long as the NFC cards are used properly.

IJARCCE - Computer and Communication Engineering

4 Abstract: Mobile devices have larger impact in our daily life. The proposed project is concerned with ticketing and identification of the passenger in the public transport service. As seen in various metropolitan cities like Mumbai, Kolkata, Chennai, Bangalore there are various issues and problems related to severe malfunction and security. There are various problems related to public transport like confusion and misunderstanding between the passengers regarding fares, facing the severe problem of traffic jam, having severe security problems in public transport due anti social elements. This proposed project aims to develop a user friendly, interactive automated ticketing system which will deduct the passenger's fare according to the distance travelled as well as detect the passenger's identification. This is only possible by use of Near Field Communication (NFC) cards. The project is developed using NFC technology. This project provides a NFC system that can identify passengers in public transport as well as it does all accounting purpose based on travelling fares. Automated and accurate accounting of bus transport can be used to provide useful estimates of the fare of travelling from one bus stop to another as well as the crowd density can be measured inside the bus, but in case of India measuring crowd density is of no use. Near field Communication (NFC) tags is going to be used in this project. Passenger would carry NFC card with them, when they enter into the bus they have to show the NFC card to the Conductor. The conductor will use NFC based android cell phone to read the NFC tag. Based on the distance travelled the cost would be automatically deducted. Near Field Communication is a wireless technology which allows transmitting data between two devices. NFC commonly integrated within mobile devices. This will allow the device to establish communication with another device sim card. So it can be used as a substitute of wallet in public transportation. Basically NFC has 2 different modes of data transmission:
