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.

A barcode is a series of lines and numbers that you see on packaging of products. The barcode is machine-readable and provides information such as description and price of… the product.
so the detectors at every opening of the shop can detect them and this is a good way of preventing any thefts, bbut the disadvantage is tat if the clothe is stripped of …its barcode then nicked the detectors wont detect them because there is no bar code onj the clother. hope this answered ur question and am sorry if it didnt and was unhelpfull or wrong.
The first patent for a bar code type product (US Patent #2,612,994) was issued to inventors Joseph Woddland, Jordin Johanson and Bernard Silver on October 7, 1952. It …was not until 1966 that barcodes were put to commercial use and they were not commercially successful until the 1980s.

A barcode contains the ID number of the product, which can be used by cash registers to gather information from the server such as it's price, and name.
If you need to get a UPC (Universal Product Code) now known as GS1 for the purpose of selling your items in a retail Establishment that demand it, then you will need to regist…er with GS1 and get the bar codes from them. Other bar codes are very simple to get. Lets assume you need to get a bar code for your product ID. Use any label design program (I recommend NiceLabel Evaluation Software), simply choose the TYPE of bar code you want and give it the information you want to convert to bar code, such as Product ID and the software will do the rest. It will automatically generate the correct format of the bar code you need.

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.
For the same reason they're on just about everything - stock control.
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 sensor tr…anslating 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).
