Bar Code Technology Presentation Transcript
1. BAR CODE TECHNOLOGY AND ITS APPLICATION TO LIBRARY SERVICES
2. BAR CODE TECHNOLOGY
It is an automatic identification technology
Bar code is a predefined format of dark bars and white spaces
Structured to contain a specific piece of information
It allows real-time data to be collected accurately and rapidly
Combination of barcode technology with computer and application software improves performance, productivity and profitability
3. Discrete Symbology
4. Continuous Symbology
5. DATA ENTRY TECHNIQUES
6. BENEFITS OF BAR CODING
REPRESENT UNIQUE IDENTITY OF A PRODUCT
ACCURACY OF DATA INPUT (ERROR FREE)
AID EFFECTIVE MANAGEMENT OF RESOURCES AND INVENTORIES
LABOUR SAVINGS BY AVOIDING MANUAL SYSTEM
7. COST EFFICIENT
REAL TIME DATA COLLECTION
MEASUREMENT OF WORK IN PROGRESS THROUGHOUT THE FACTORY
RAPID ACCESS TO TOTAL PRODUCTION COSTS
MORE ACCURATE DESPATCH
8. 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
9. TERMINOLOGY
HAND-HELD SCANNER
A scanner held and operated by a human operator
INTER-CHARACTER GAP
The space between the bars or spaces
MOVING BEAM SCANNER
A Bar Code scanner that uses a moving light beam to dynamically scan and decode a Bar Code symbol
10. 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
11. Bar-code system
12. Thermal Transfer Printer
13. BAR CODE SCANNERS
A device used to extract information optically from a Bar Code
Bar Code symbol consists of series of vertical dark bars separated by light spaces
When illuminated reflected light is detected by electro optical sensor
The intensity of reflected light from the dark bars is less than that of spaces
14. SCANNERS
Reflected light is converted into electrical voltage signals
Analog voltages are digitized into raw data
The decoder converts this data into the character data representation of the symbol’s code
15. TYPES OF SCANNERS (READERS)
CONTACT READERS
Must touch or come in close proximity of symbol
Good where the label cannot be placed in an easy-to-view position
Normally hand-held/stationary units
Common type is pen/wand reader
A high-density resolution wand used to read a low-density symbol might see an ink spot as bar or an ink void as a space
16. CONTACT READERS
A low-resolution wand may not be able to recognise a narrow bar of high-density symbol
Positioned angle of wand to the surface and movement speed across the symbol are key parameters
17. Contact Readers
18. NON-CONTACT READERS
Reader need not come in contact with symbol
Scan distance may be from 6” to several feet depending upon symbol size and scanner design
Hand-held, fixed beam readers
19. Table mounted fixed beam reader
20.Table mounted fixed beam reader
21. Hand-Held moving beam readers
22. Fixed beam slot scanner
23. CCD Scanner
24. Portable Data Collection Equipment
25. BAR CODE APPLICATIONS
INVENTORY CONTROL
Portable readers
WORK-IN PROCESS TRACKING (WIP) COMPANY INVENTORY
Raw materials
WIP (Components, Assemblies, Semi finished Products)
Finished Products
26. APPLICATIONS
SHIPPING
ELECTRONIC DATA INTERCHANGE (EDI)
Direct communication between computers of two companies (Manufacturer & Vendor)
Industry-wide EDI standards
Reduces cost and saves time of business transaction
27. RETAIL APPLICATIONS
Super markets
Counter-mounted Bar Code scanners
Universal Product Code (UPC)
Price and description information
WARE HOUSING
HEALTH CARE APPLICATIONS
Drugs, devices, instruments
Identification of expiry date
Blood banking
Blood group
Expiry date
Donor traceability
28. APPLICATIONS
29. BAR CODING IN LIBRARIES
EFFECTIVE LIBRARY NEEDS EACH DOCUMENT BAR CODED
TWO LABELS PREFERABLY
LABEL TO CONTAIN
Accession number equivalent Bar Code
Call number
Institution logo advantageous
ISBN BAR CODE COULD BE USED
30. DATABASE PROGRAM LINKS THE BAR CODE TO BIBLIOGRAPHIC DETAILS OF DOCUMENTS
AUTHORISED ID CARD INCLUDES BAR CODE
Card could be used by library
Institutional ID card
Social security number
BAR CODE READER INTERFACED TO COMPUTER
TRACKING OF BOOKS
31. INCORPORATING BAR CODE IN LIBRARIES
THE TYPICAL SEQUENCE WOULD BE
Database creation (OPAC)
Generate Bar Code for all transact able documents
Bar Code membership cards
Installation of suitable scanning equipment
Set different criteria for transactions
32. ADVANTAGES OF BAR CODE IN LIBRARIES
Quick and error free entry of access and membership codes
Ensures total integrity of collected data
No queuing up at check out/check in counters
Avoids piling up of data entry work for counter staff
Aids generation of suitable reminders to delinquent borrowers
Stock verification made easy
