Barcode Technology Presentation Transcript:

1. BAR CODE TECHNOLOGY
BAR CODE TERMINOLOGY Types of barcode BAR CODE SCANNERS Types of scanners BENEFITS OF BAR CODING

2. BAR CODE TECHNOLOGY
It is an automatic identification technology Bar code is a predefined format of dark bars and white spaces It contain a specific information It allows real-time data to be collected accurately and rapidly Combination of barcode technology with computer and application software improves performance, And productivity

3. BAR CODE TERMINOLOGY
BAR - The darker, non reflective element of a Bar Code BI-DIRECTIONAL SYMBOL - A Bar Code symbol format which permits reading in either direction across the bars and spaces CHECK DIGIT - A calculated character included within the Bar Code for error detection FIXED BEAM SCANNER - A stationary Bar Code Scanner. The symbol must be moved through the light beam to be read

4. TERMINOLOGY …
SPACE The lighter, reflective element of a Bar Code START CHARACTER A special pattern of bars and spaces used to identify the beginning of a Bar Code symbol STOP CHARACTER A special pattern of bars and spaces used to identify the end of a Bar Code symbol

5. Types of barcode
Alpha-numeric barcodes Numeric-only barcodes 2-Dimensional barcodes

6. Numeric-only barcodes UPC-
A: - Universal product code seen on almost all retail products in the USA and Canada EAN-13: - European Article Numbering international retail product code Codabar: - Older code often used in library systems, sometimes in blood banks

7. EAN-13
EAN-13 is used world-wide for marking retail items . EAN-13 is used where the country code is required. This code is composed of 2 numbers for country code 10 numbers for data characters and one for checksum. The checksum calculation: Add the values of the digits in the even-numbered positions: 2, 4, 6, etc. Multiply this result by 3. Add the values of the digits in the odd-numbered positions: 1, 3, 5, etc. Sum the results of steps 2 and 3. The check character is the smallest number which, when added to the result in step 4, produces a multiple of 10.

8. Alpha-numeric barcodes Code 128: 
Very capable code, excellent density, high reliability; in very wide use world-wide Code 39:  General-purpose code in very wide use world-wide

9. 2-Dimensional barcodes PDF417: 
Excellent for encoding large amounts of data DataMatrix:  Can hold large amounts of data, especially suited for making very small codes Maxicode:  Fixed length, used by United Parcel Service for automated package sorting
