    • AN INTRODUCTION TO BARCODE Presented By: Van Chiang
    • 1. Brief History of Barcode2. Why barcode? Advantages.3. Symbologies. - Types, Differences between 1D and 2D4. Composition of a barcode. - check digit, silent zone, human readable5. What affect scannability of barcode? - scan method, environment, print quality, print surface, color combination6. Q&A

    • Most common coding for custom usage.Can be decoded by virtually any barcode scanner.One of the oldest modern barcode.Encodes 44 characters onlyEach character is composed of nine elements:five bars and four spaces.Three of the nine elements are wide (binary value 1),and six elements are narrow (binary value 0).An additional common character (*) is used for bothstart and stop delimiters.No checksum required.Drawback is low data density, require more space toencode data.
    • High density barcode. Suitable for small products.Common for custom usage.Encode all 128 characters available in ASCII format.Have a mandatory check character maximizes data integrity.The major drawback is the barcode must be printed by higherresolution printer to be scanned correctly.
    • For use in the retail grocery industry – point of sales application. Has several good features such as check digit and good density. A limited number of characters (numeric characters only). In UPC, 1 digit for a system number,5 digits for the manufacturer number,5 digits for the product number, and one checksum digit.In EAN/JAN, 2 numbers for the country code,10 numbers for the data characters, and one checksum digit.
    • Store up to about 1,800 printable ASCII characters or 1,100 binary characters per symbol. Has three different encoding schemes that repeat every three rows. Enables the symbol to sustain considerable damage and still be readable.PDF stands for Portable Data File. A unique start and stop pattern which identifies the format as PDF417. All rows have the same number of codewords. Every codeword contains four bars and four spaces. The total width of a codeword is 17 times the width of the narrowest allowedvertical bar
    • Encode up to 3750 characters .Built on a square grid with a bullseye pattern at its center.Data is encoded in a series of "layers" that circle aroundthe bullseye pattern.Each additional layer completely surrounds the previous layerthus causing the symbol to grow in size as more data is encoded.Orientation independent scanning.Commonly used as a electronic boarding pass which is send to thehandphone, or printed out as hardcopy ticket.
    • Resemble a checkerboard pattern. Low contrast possible.Primarily used for its small size (50 characters in 2 – 3mm2)Exceptional data capacity, capable of encoding up to2335 alphanumeric characters.Consist of two solid adjacent borders in an "L" shape(called the "finder pattern") and two other borders consistingof alternating dark and light "cells“ (called the "timing pattern").The EIA recommends using Data Matrix for labelingsmall electronic components. Engraved on PCB Printed on Label
    • QR is the short form for Quick Response.Can encode numeric only, alphanumeric, binary, kanji/kana. used in a much broader context, aimed at mobile phone users (known as mobile tagging).The usage? QR Code to be read with a mobile phone.
