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.
