Does NFC keep people's information private?5 answersNFC technology raises concerns about the privacy of people's information. The security measures and technologies used in contactless payment systems, such as NFC-enabled mobile wallets and contactless POS terminals, are examined to understand the protection against security and privacy threats. The proposed Authentication Protocol for Mobile Applications using NFC technology (AP for MAN) aims to minimize the required time for authentication while ensuring a high level of privacy. Conditional privacy protection methods based on pseudonyms are proposed to address privacy issues in NFC electronic payment. The NFC-based security protocol for financial applications is designed to address security requirements and protect against various attacks, ensuring the secrecy of transaction data and privacy of users. However, the current NFC security standards are deemed inadequate to address all security concerns, including privacy infringements and unauthorized access to financial data.

What is credit?5 answersCredit is the provision of loan money based on an agreement or loan agreement between the creditor and other parties. It involves the lending of money or bills that can be equated with it. Credit can be seen from various perspectives, including as a means of providing loans to parties in need and as an activity of borrowing, lending, and deferred payment in economic activities. It is governed by mutual trust and is based on honesty, trustworthiness, and the ability to fulfill obligations. Proper systems and procedures are necessary in providing credit to reduce the occurrence of non-performing loans. Credit analysis plays a crucial role in assessing the creditworthiness of borrowers. Various methods, such as Multi-Objective Optimization On The Basis Of Ratio Analysis (MOORA), Logistic Regression, and Support Vector Machines, can be used to analyze creditworthiness.
What is Radio Frequency Identification (RFID)?5 answersRadio Frequency Identification (RFID) is a technology that uses electronic tags to store data and transmit it through radio waves to RFID readers. It is a subset of automated identification technologies and does not require human intervention. RFID systems provide real-time identification tracking and monitoring, enabling access control and inventory management solutions. They can also be combined with Geographic Information Systems (GIS) to track both identity and spatial location. RFID tags can be attached to animate or inanimate objects, and RFID readers translate the data into meaningful information. RFID tags can be in a standby state to conserve power and switch to a normal working state when moved. The technology has been applied in various fields such as logistics, manufacturing, and university asset management.
What is semiconductor?4 answersA semiconductor is a material that forms the basis for the nano-electronics industry and is essential for everyday life. It has electronic band structure, lattice dynamics, and transport properties that are studied at the graduate level. Semiconductors are used in devices that have input/output circuits, power lines, resistance elements, and capacitance elements to control signal input/output and suppress resonance phenomena and voltage variation. Compounds adsorbed on the surface of semiconductors can negatively change the flat band potential of the semiconductor. Semiconductor research has played a central role in basic, applied, and computational science, leading to advancements in transistors, integrated circuits, solar devices, and lasers. Semiconductors are also used in plating layers that bond substrates and electrodes in semiconductor units.
What is Android?4 answersAndroid is a mobile operating system developed by Google and based on the Linux kernel. It is designed primarily for touchscreen mobile devices such as smartphones and tablets. Android consists of four main layers: the kernel, libraries, application framework, and applications. It also includes key applications and middleware. The operating system uses touch inputs and gestures to manipulate on-screen objects, along with a virtual keyboard for text input. Android is an open source platform, allowing for the development of a wide range of applications. It is widely used and has a large market share, with millions of customers worldwide.
