A barcode is an optical machine-readable representation of data, which shows certain data on certain products. Originally, barcodes represented data in the widths (lines) and the spacing of parallel lines, and may be referred to as linear or 1D (1dimensional) barcodes or symbologies.

 Two types of Barcode
One Dimensional Barcode(1D)

  • However, the vertical redundancy allows a symbol with printing defects, such as spots or voids, to still be read. The higher the bar heights, the more probability that at least one path along the bar code will be readable.
  1. Two Dimensional Barcode(2D)
    1.  A two-dimensional code stores information along the height as well as the length of the symbol
    2.  Since both dimensions contain information, at least some of the vertical redundancy is gone.
    3. Other techniques must be used to prevent misreads and to produce an acceptable read rate. Misread prevention is relatively easy.
    4. Most two-dimensional codes use check words to insure  accurate reading.
    5.  Acceptable read rate is a different problem, and no research has been done to date to assess first read rates.

Different Type of 2D Barcode :

  • QR Code
  • Data Matrix Code
  • Aztec Code
  • Maxi Code


  • Barcode in various vertices:
  • Library Management System

          A Biometric System is a system for the automated recognition of individuals based on their behavioral and biological characteristics.

          • Biological Characteristics

                      ex : Fingerprints, face geometry, iris patterns and hand geometry

          • Behavioral Characteristics

                      ex : dynamic signature recognition

          • Biometric systems consists of three steps:
          • Enrollment:
          1. records basic information ie., name or an identification number.
          2. It then captures an image or recording of your specific trait.
          • Storage:
          1. Systems don't store the complete image or recording.
          2. They analyze your trait and translate it into a code or graph.
          3. This data can also be recorded onto a smart card.
          • Comparison:
            • It compares the trait you present to the information on file.
            • Then, it either accepts or rejects that you are who you claim to be.

            Biometric cum RFID Reader

            • Biometric cum RFID reader can be used as an integrated system where in an authorized personnel is allowed to enter the premises or mark his attendance.

            Point of sale (POS) (also sometimes referred to as Point of purchase (POP) ) or checkout is the location where a transaction occurs. A "checkout" refers to a POS terminal or more generally to the hardware and software used for checkouts, the equivalent of an electronic cash register.
            A POS terminal manages the selling process by a salesperson accessible interface. The same system allows the creation and printing of the receipt.
