NFC no need to launch an application .....................it just works! What is NFC ? How it works ? NFC stands for Near Field Communication, is a set of short-range high frequency wireless technology that establish radio communication with each other when bringing them into proximity, typically requiring a distance of 4 to 8 cm or less. NFC allows to share small amount of data between  NFC enabled devices and NFC tag or two android-powered NFC devices. You would also like to know about -   Sensor  ,  AMOLED display   ,  Biometrics ,  Smart card NFC standards cover communication protocols and data exchange formats, and are based on existing radio-frequency identification (RFID). Unlike Bluetooth, no pairing code is needed, and because it's very low power, no battery in the device can be read. An NFC tag (essentially "targets" that "want" to be touched by NFC device like cellphones) can share and link to information such as set pro...

When new technology developed, the one term which always strikes in mind is what sensor does it include to process. Sensors becoming most common but important in today's world covering all physical stimulus like light, heat, sound, pressure etc. Here, we are going to discuss about Infrared sensor - what is it , how does it work and what are the application areas. What is Sensor ? A Sensor is a device / converter that detects input from the physical environment and converts it into a signal which can be read by an observer or by an electronic instrument. A sensor responds to an input quantity by generating a functionally related output usually in the form of an electrical or optical signal. A sensor's sensitivity indicated how much the sensor's output changes when the measured quantity changes.  The specific input could be light, heat, motion, moisture, pressure or other physical stimulus. Examples -  Blood pressure meter - Device used to measure blood p...

You've heard the AMOLED term bunch of time when talking about the smartphones, or try to find out the characteristic difference while comparing with other mobile devices. Whether you already know AMOLED or not, here at ATCAPH you will find the complete information about AMOLED so that when someone says that its mobile having some sort of AMOLED, you know what exactly they are talking about. What is AMOLED ? AMOLED, stands for active-matrix organic light-emitting diode . It is a hybrid display technology that pairs the active matrix backplane from a traditional TFT display with an OLED display. OLED describes a specific type of thin-flim-display technology in which organic compounds from the electroluminescent material, and active matrix refers to the technology behind the addressing of pixles. Each pixel has an active element (a thin-film transistor, or TFT) that actively provides current to the OLED, maintaining that pixel's brightness while the other pixels are...

Introduction        (5 mark question) A Smart Card , Chip Card, or Integrated Circuit Chip (ICC) is any pocket-sized card with embedded integrated circuits, smart card is a plastic card about the size of a credit card, with an embedded microchip that are loaded with data used for telephone calling, electronic cash payments, and other applications, and then periodically refreshed for additional use. ' Fig 1 : Smart card chip structure and packaging Smart card can provide identification , authentication , data storage and application processing. Smart cards may provide strong security authentication for single sign-on (SSO) within large organizations. Smart card are suitable for personal identification tasks, the chip is implemented with some cryptographic algorithm.
