  1. 1. BARCODEVaishnavi C
  2. 2. What is Barcode ?• A barcode is an optical machine-readable representation of data relating tothe 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 deliveredto each desk or location within an office. to help security guards identify every employee, every door they enter andevery 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. 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. 4. • Each product must have a unique product item number so that the systemcan keep up with it else it can wreak havoc on both the pricing andinventory system.• It is the UPC coordinator’s job to make sure mistakes as such do nothappen.• Check digit is the final number on the barcode label, when scanner readsthe barcode, the check digit helps it verify that the barcode has been readcorrectly.
  5. 5. How does a barcode work?• Once the barcode is run across the scanner, the scanner picks up thebarcode.• 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 usedwhen 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 acomputer, or register, then it finds the record associated with it.• The computer records may contain the information such as price, numberof items currently available, and other pertinent information like that.
  6. 6. Barcode Technology• No matter what type of business we run, chances are still high that barcodetechnology 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 effectivedecisions in a quicker amount of time.• Barcodes have the ability to collect more data at a much faster rate thanemployees.• This allows management and those involved in decision making processesimmediately access to valuable information.
  7. 7. • The most common reason for businesses to employ barcode technology isfor 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 collectinformation.• Often employees can make errors in record keeping.• By implementing the barcode technology in businesses, we will most likelyimprove the accuracy of the records.
  8. 8. Barcode Recognition• The barcode developers create a new barcode, then the number and symbolare scanned onto a laser paper, and then are imprinted on to the back ofproduct labels.• Each grocery chain or manufacturer has its own system for barcoderecognition.• Before a cash register can recognize a particular code, information aboutthe entire inventory must be included within the memory.• On a corporate level, there is a person responsible for keying or recordingpricing information.
  9. 9. • Thus, if a product is on sale or promotional items are available, the registerwill automatically notify clerk at checkout.• Of course, glitches can occur within the system, which makes barcoderecognition difficult.• For example, barcodes can be spaced too far apart or too close.• Because of low printing resolution, barcodes may not accurately transferonto paper.• This could also present problems when the barcode is scanned.
  10. 10. • 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 symboland 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.
