BARCODE
Vaishnavi C
What is Barcode ?
• A barcode is an optical machine-readable representation of data relating to
the object to which it is attached.
• Bar codes can be used in every business around the world. For example:
 to track assets in any building including every desk, computer, telephone,
copier and desk accessory.
 To track mail from the time it arrives in the mail room to the time it is delivered
to each desk or location within an office.
 to help security guards identify every employee, every door they enter and
every room they work in.
 to secure, lock or unlock entrances or exits throughout the plant.
 to manage and track your vehicle fleet and each driver
How is it generated?
• Barcode Labels are used on most products today.
• Each barcode label has a few different parts.
• They can be classified as:
 Manufacturer’s ID.
 Product Item Number.
 Check Digit.
• The first six number seen on the label represent the manufacturer’s ID.
• The next set of five numbers is the product Item number.
•
• Each product must have a unique product item number so that the system
can keep up with it else it can wreak havoc on both the pricing and
inventory system.
• It is the UPC coordinator’s job to make sure mistakes as such do not
happen.
• Check digit is the final number on the barcode label, when scanner reads
the barcode, the check digit helps it verify that the barcode has been read
correctly.
How does a barcode work?
• Once the barcode is run across the scanner, the scanner picks up the
barcode.
• This is done by reading the bars and spaces between the bars.
• The numbers at the bottom of a UPC label are for humans only, this is used
when the UPC label is either torn or is unrecognized by the scanner.
• As the scanner picks up the bars, it then transfers the information to a
computer, or register, then it finds the record associated with it.
• The computer records may contain the information such as price, number
of items currently available, and other pertinent information like that.
Barcode Technology
• No matter what type of business we run, chances are still high that barcode
technology can help make our job a little easier in one way or another.
• One of the greatest benefits it provides is the ability to make effective
decisions in a quicker amount of time.
• Barcodes have the ability to collect more data at a much faster rate than
employees.
• This allows management and those involved in decision making processes
immediately access to valuable information.
• The most common reason for businesses to employ barcode technology is
for the reduction in labor costs.
• More work can be achieved in less time and with fewer employees.
• This technology is considered to be the more accurate way to collect
information.
• Often employees can make errors in record keeping.
• By implementing the barcode technology in businesses, we will most likely
improve the accuracy of the records.
Barcode Recognition
• The barcode developers create a new barcode, then the number and symbol
are scanned onto a laser paper, and then are imprinted on to the back of
product labels.
• Each grocery chain or manufacturer has its own system for barcode
recognition.
• Before a cash register can recognize a particular code, information about
the entire inventory must be included within the memory.
• On a corporate level, there is a person responsible for keying or recording
pricing information.
• Thus, if a product is on sale or promotional items are available, the register
will automatically notify clerk at checkout.
• Of course, glitches can occur within the system, which makes barcode
recognition difficult.
• For example, barcodes can be spaced too far apart or too close.
• Because of low printing resolution, barcodes may not accurately transfer
onto paper.
• This could also present problems when the barcode is scanned.
• For the most part, barcode development software is useful.
• Problems typically arise from printing.
• Once a barcode has been printed, it helps to carefully inspect the symbol
and numbers.
• Make sure that the printed copy is identical to the original barcode.
• If necessary, adjust the space between bars.
• This eliminates potential problems with barcode recognition.

Barcode

  • 2. What is Barcode ? • A barcode is an optical machine-readable representation of data relating to the object to which it is attached. • Bar codes can be used in every business around the world. For example:  to track assets in any building including every desk, computer, telephone, copier and desk accessory.  To track mail from the time it arrives in the mail room to the time it is delivered to each desk or location within an office.  to help security guards identify every employee, every door they enter and every room they work in.  to secure, lock or unlock entrances or exits throughout the plant.  to manage and track your vehicle fleet and each driver
  • 3. How is it generated? • Barcode Labels are used on most products today. • Each barcode label has a few different parts. • They can be classified as:  Manufacturer’s ID.  Product Item Number.  Check Digit. • The first six number seen on the label represent the manufacturer’s ID. • The next set of five numbers is the product Item number. •
  • 4. • Each product must have a unique product item number so that the system can keep up with it else it can wreak havoc on both the pricing and inventory system. • It is the UPC coordinator’s job to make sure mistakes as such do not happen. • Check digit is the final number on the barcode label, when scanner reads the barcode, the check digit helps it verify that the barcode has been read correctly.
  • 5. How does a barcode work? • Once the barcode is run across the scanner, the scanner picks up the barcode. • This is done by reading the bars and spaces between the bars. • The numbers at the bottom of a UPC label are for humans only, this is used when the UPC label is either torn or is unrecognized by the scanner. • As the scanner picks up the bars, it then transfers the information to a computer, or register, then it finds the record associated with it. • The computer records may contain the information such as price, number of items currently available, and other pertinent information like that.
