Barcoding and other identification

systems in packaging

• A barcode (also bar code) is a machine-readable

representation of information

• Barcodes can be read by optical scanners called barcode

readers or scanned from an image by special software.for

eg RS-232 barcode scanner, Keyboard interface scanners,

USB scanners

• Barcodes are widely used to implement Auto ID Data

Capture (AIDC) systems that improve the speed and

accuracy of computer data entry.

Barcoding

WHY BARCODES ?

* To enable data capture

- For 100% accuracy and high speed.

- Generation of automated billing, packing

lists, delivery challans etc.

- Effective product track & trace

Barcode types

There are two types of barcodes: Linear barcodes and 2D barcodes. Some examples include:

Linear barcodes 2D barcodes

Code 128 Data Matrix

UPC Dot code

Interleaved 2 of 5 QR code

Universal Product Code: Main

Universal Product Code: Built

in Checks

• Check Digit Calculation: Exampleo Sum odd digits (1, 3, 5..)

• 6+9+8+0+0+9 = 32

o Multiply this by 3• 32*3 = 96

o Sum even digits (2, 4, 6..)• 3+3+2+0+3 = 11

o Add this to value in Step 2• 96+11 = 107

o Determine then number that added to the above value would generate a multiple of 10• 107 + 3 = 110

• Therefore 3 is our Check Digit

QR code (abbreviated from Quick Response Code) is a

type of matrix barcode (or two-dimensional barcode) first

designed for the automotive industry in Japan.

The QR Code system has become popular outside

the automotive industry due to its fast readability

and greater storage capacity compared to standard

UPC barcodes.

Applications include product tracking, item

identification, time tracking, document

management, general marketing, and much more

HOW TO READ BAR CODES

- Distribution (Product track and trace, information flow)

- Manufacturing (Inventory control, raw material procurement, work-in-progress, dynamic production scheduling)

- Customer Satisfaction (Low product prices, quick replenishment, faster checkouts)

- Exports- In line with buyers requirements- Product track and trace

Applications

Usage of Barcoding in India – current status

•Automobile Industry–for inventory management/ track &

trace/production scheduling.

•Readymade garments Industry – for inventory

management/track & trace/production scheduling.

•Pharmaceutical Industry – for inventory management / track &

trace/production scheduling.

•Retail Industry – Grocery, etc.

•Exports (on buyers directives)

•Healthcare (hospitals etc)

The example production line seen below has been simplified. Thisproduction line is for the assembly of a bicycle. As the bicycle frametravels down the production line each person at a workstationworkstation has a specific task to carry out ( see below). Eachcomponent/part has a barcode, ensuring the computer system cankeep track of the products progress, along the production line.

Retailers / shops / catalogues. A checkout operator in a supermarket scans a product barcode as the customer passes through the checkouts. The price will be automatically displayed and as more products are checked out the total cost will be calculated. This means the checkout operator does not need to manually type in the price of each product. This makes the checkout procedure less time consuming and it is less likely that mistakes will happen.

Advantages of barcode• Speed and accuracy

• Barcodes promote better decision making.

• System costs are lower than other means of data entry because of the existence of interfacing hardware and software.

• Barcode systems create value not only by saving time, but also by preventing costly errors.

• Using a barcode system reduces employee training time. It takes only minutes to master the hand-held scanner for reading barcodes.

• Barcodes are inexpensive to design and print

• Data obtained through barcodes is available rapidly.

disadvantages of barcode• Data must be coded in barcode

• They are very labour intensive; as they must be

scanned individually.

• If a barcode is damaged there is no way to scan the

product.

• Scanning Problems

The Future:

Radio Frequency Identification system

What is RFID?• RFID stands for Radio-frequency identification (RFID ) an

Auto-ID data collection.

• It is an automatic identification method, relying on storing and

remotely retrieving data using devices called RFID tags or

transponders.

• Is fast and does not require physical sight or contact between

reader/scanner and the tagged item.

• invented in 1948 by Harry Stockman.

• Initial application was during World War II

Working• A radio device called a tag is attached to the object that needs

to be identified.

• When this tagged object is presented in front of a suitable

RFID reader, the tag transmits this data to the reader (via the

reader antenna).

• The reader then reads the data and has the capability to

forward it over suitable communication channels.

• This application can then use this unique data to identify the

object presented to the reader.
