Smart Card Technology

-
Smart card is a pocket-sized plastic card with a small chip inserted into it. It is also known as a readable device which provides security verification in large organizations. It can store and transmits and records data to a central computer whenever needed.
Smart card is a special type of card like device which contains an integrated circuit chip embedded on it. The IC chip can be a microprocessor with memory or just simple memory circuit. 
Smart cards have three main functions: authentication, storing personal information, and storing values.
Smart card-enhanced systems are in use today in several key applications such as health-care, banking, entertainment and transportation. The card data is transacted via a reader connected to a computing system.

How does the Smart Card Works?




Smart card reader is also called as a card acceptance device, or an interface device. There is a minute difference between the card reader and the terminal. The reader is used to determine a unit that interfaces with a computer or microcontroller for all of its processing requirements. Similarly a terminal is also considered as a self- contained processing device. It can be contact type or non-contact type.
A smart card is connected to the host computer or controller via a card reader which gets information from the smart card and accordingly passes the information to the host computer or controller.

    The most common applications of Smart cards are:
    • Electronic cash
    • Computer security systems
    • Credit cards
    • Wireless communication
    • Banking
    • Satellite TV
    • Ecommerce and Retail
    • Transporation
    • Telecommunications
    • Government identification

    What Is Global Positioning System - Introduction To GPS - How It Works

    -
    Image
    The Global Positioning System (GPS) is a satellite-based navigation system made up of at least 24 satellites. GPS works in any weather conditions, anywhere in the world, 24 hours a day, with no subscription fees or setup charges. The U.S. Department of Defense (USDOD) originally put the satellites into orbit for military use, but they were made available for civilian use in the 1980s. GPS or Global Positioning System is a network of orbiting satellites that send precise details of their position in space back to earth. The signals are obtained by GPS receivers, such as navigation devices and are used to calculate the exact position, speed and time at the vehicles location. GPS is well-known for its military uses and was first developed by the US to aid in its global intelligence efforts at the height of the Cold War. Ever since the early 1980s, however, the GPS has been freely available to anyone with a GPS receiver. Airlines, shipping companies, trucking firms, and drivers

    1971 January 30 : An Indian Airlines plane on its way from Srinagar to Jammu was hijacked by Hashim Quereshi and Ashraf Quereshi of the JKLF, who took it to Lahore. Zulfikar Ali Bhutto, then Foreign Minister of Pakistan rushed to Lahore and met the hijackers and helped them get maximum international publicity. On February 1, he persuaded them to release the crew and passengers who were then sent by road to Amritsar. The Government of India sought permission of Pakistan to send a replacement crew to fly the aircraft back to India. Pakistan authorities denied the permission. Instead it is alleged they supplied petrol to the hijackers with which they burnt the aircraft on February 2. From Lahore Airport the hijackers were taken into a procession as heroes. 1981 September 29 : An Indian airlines plane on flight from Srinagar to Delhi is hijacked by Sikh Terrorists and taken to Lahore. Pakistan took commando action and got all passengers released. 1982 August 22 : A lone mili

    The Benefits and Risks of Ultra-Violet Radiation

    Ultraviolet (UV) radiation is a type of energy produced by the sun and some artificial sources, such as solariums.  Ultra-violet (UV) lasers for Raman spectroscopy typically include laser wavelengths ranging from  244 nm through to 364 nm . UV radiation isn’t like the sun’s light or heat, which we can see and feel. Your senses cannot detect UV radiation, so you won’t notice the damage until it has been done. Theoretically UV Raman spectroscopy is no different from standard analysis using visible laser wavelengths.  However, in practice there are a  small amount that gets through has both positive and negative effects.  Positive effects of UV Photolithography:  UV is employed in fine resolution photolithography and hence is extensively used in the field of electronics. Vitamin D Production :  UV from the Sun is needed by our bodies to produce vitamin D. Vitamin D helps strengthen bones, muscles and the body’s immune system. It may also lower the risk of g
