3. What is barcode?
 It is an automatic identification technology
 Bar code is a predefined format of dark bars and white
spaces

4. Why use barcodes?
 As far back as the 1960s, barcodes were used in

2. 2D barcodes.

6. Applications of barcode
 For laboratories
 For Libraries
 For Industry
 Health agencies
 Document Tracking
 For departmental stores

7. Barcode Scanner
Handheld, single line
Handheld, single line
Fixed mount, multi-line

8. Advantages
 REPRESENT UNIQUE IDENTITY OF A
PRODUCT
 ACCURACY OF DATA INPUT (ERROR
FREE)
 LABOUR SAVINGS BY AVOIDING
MANUAL SYSTEM
 MORE ACCURATE DESPATCH
 COST EFFICIENT
 REAL TIME DATA COLLECTION
 MEASUREMENT OF WORK IN
PROGRESS THROUGHOUT THE
FACTORY
 RAPID ACCESS TO TOTAL PRODUCTION
COSTS

9. Disadvantages
 System Failure may cost more delays.
 Scratched or crumpled barcodes may cause problems
 Data must be coded in the barcode
 In laser scanning, durability and cost are the two
disadvantages
