How do barcodes work?
Bar codes were created to help grocery stores speed up the checkout process. UPC bar codes,which stand for 'Universal Product Code' were first used in grocery stores. Every store item needs a different code so that it can be scanned correctly. The last digit of a UPC bar code is called the check digit and is calculated by the other 11 digits. For example, if you were to find the check digit for the UPC code 63938200039...: 1.) Add together all the digits in odd positions (1,3,5,7,9,11) 6 + 9 + 8 + 0 + 0 + 9 = 32 2.) Multiply the number by 3 32 x 3 = 96 3.) Add together all the digits in even positions (2,4,6,8,10) 3 + 3 + 2 + 0 + 3 = 11 4.) Add the sum to the value in Step 2 96 + 11 = 107 5.) Take the answer 107. To create the check digit, determine the number that, when added to the number 107, is a multiple of 107 107 + 3 = 110 So, the check digit is 3. A Barcode is an optical machine-readable representation of data.

Other bar codes are very simple to get. Lets assume you need to get a bar code for your product ID.

The simple answer is that a barcode is a code that a contains information in the form of bars. This information is printed and then scanned (read) by a scanner that can decode… the message in the bars and convert it back to the original information. One of the most widely used ways of using barcodes is the UPC (Universal Product Code) that is the barcode we all see at the grocery store on every product we buy. The barcode contains a series of numbers that represent the manufacturer code as well as information about the product itself. When the scanner "reads" the barcode into the POS (point of sale) system, it matches the actual number with the item description and price. The output of this simple action is the printing of your receipt with the item code, description and price you paid for it. There are many types of barcodes, simple ones as the ones described above that contain only one type of information and more complex ones containing many pieces of information.
A barcode reader (or barcode scanner ) is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light senso…r translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.
If you go to a shop and pick up almost any product (say a tin of beans), then if you look at the label on the tin you will see a small rectangle printed on it made up of black… lines separated by spaces. These black lines are the barcode and when scanned by a computer laser the pattern formed by the bars can be read as a number. The number is unique to the product and this enables the checkout till to find the price for the product and the store to update its stock records (to order another tin to replace the one sold).
Barcodes were initially designed and is still used today as ainventory tracking method by companies to keep tabs on stockavailability on their products, as well as for logisti…cs (forcouriers like post offices and private couriers like UPS). With thesmartphone revolution with barcode scanner apps that supporttwo-dimensional barcodes, these new barcodes can store moreinformation than just stock inventory numbers - now they can beused to store addresses and web links (e.g. the common types wouldbe Data Matrix and QR code).
If you own a company or are looking to start getting barcodes isdefinitely a must. The most common way to get a barcode is to lookup and register your product with a place cal…led GS1. There mightbe other ways but GS1 is the most common route to go.
