A smart card, a type of chip card is a plastic card embedded with a computer chip that stores and transacts data between users. The card data is transferred via a reader that is part of a computing system. Smart card-enhanced security systems are in use today throughout several key applications, including healthcare, banking, entertainment and transportation.
Application of Smart Card Payment System A payment function is an integral part of most smart card applications because most services accessible by smart cards must be paid one way or the other. Smart Networking Smart card technologies provide strong security through encryption as well as access control, based on identification technologies such as biometrics. Many countries all over the world are trying out, and implementing, the smart card option as a national identity card.
University Identification The traditional student ID card can be replaced by an all-purpose chip-based student ID card, containing a variety of applications such as electronic purse for vending and laundry machines , and for use as a library card, and meal card. Smart cards are plastic cards that contain a computer chip. Smart cards store larger amounts of information than magnetic stripe cards.
They can also update this information and secure it at a higher level than a magnetic stripe. Attached Files for Direct Download. Im a final year student ECE. In , the UPC barcode was born. To the average person, the barcode looks confusing and complex, but to a 'bar-coded' friendly computer, it's actually very simple. Bar codes provide a simple and inexpensive method of encoding text information that is easily read by inexpensive electronic readers.
Bar coding also allows data to be collected rapidly and with extreme accuracy. A bar code consists of a series of parallel, adjacent bars and spaces. Predefined bar and space patterns are used to encode small strings of character data into a printed symbol. Bar codes can be thought of as a printed type of the Morse code with narrow bars and spaces representing dots, and wide bars representing dashes. A bar code reader decodes a bar code by scanning a light source across the bar code and measuring the intensity of light reflected back by the white spaces.
The pattern of reflected light is detected with a photodiode which produces an electronic signal that exactly matches the printed bar code pattern.
This signal is then decoded back to the original data by inexpensive electronic circuits. Due to the design of most bar code it does not make any difference if you scan a bar code from right to left or from left to right. The basic structure of a bar code consists of a leading and trailing quiet zone, a start pattern, one or more data characters, optionally one or two check characters and a stop pattern.
There are a variety of different types of bar code encoding schemes, each of which were originally developed to full fill a specific need in a specific industry. The different symbologies have different capabilities for encoding data. For example the UPC symbology used to identify retail products always contains 12 numeric digits. These type of bar codes are called 'linear symbologies' because they are made up of a series of lines of different widths.
Most commercially available bar code scanners are able to read all of the different linear bar code symbologies therefore you do not need different readers for different types of bar codes. The newer 2D bar code symbologies typically require special bar code readers that are designed specifically for reading them. The magnification size of the bar code symbol is determined by the X-dimension one narrow module width in relation to a nominal size.
The allowable magnification range depends on the symbol type and the intended scanning environment.
