Disregard the first and last bar, they mark the beginning and end of the bar code. Each digit in a bar code is made up of 2 tall and 3 short bars, starting with the second bar read 5 bars as 7,4,2,1,0. which ever numbers has the tall bars add them to get the first digit of the bar code. 7 and 4 is 0.
A bar code is a type of mark which is encoded within a computer database to result into a specific commodity. When the computer reads the bar code through an optical mark recognizer(OMR) then the data of that particular commodity is highlighted.Once it is sold the computer just minuses the amount of barcodes left by one.

UPC is an universal product code and just about every item you buy comes with one. Every code for every item is different. It is put into the system by a UPC coordinator and when a UPC reader scans the code it can then keep track of inventory.
It is a common misconception that every barcode holds the number 666. This myth likely stems from the association of the number 666 with the biblical concept of the "mark of the beast" in the book of Revelation. However, barcodes are simply a representation of numbers or characters that can be scanned and interpreted by a barcode reader. The numbers encoded in barcodes are not inherently linked to any specific meaning or symbolism.
Every single code is unique so once a working code is entered, that code won't work again...so you will just have to get lucky tbh
Almost every product on sale - from a pen to a wide-screen tv has it's own unique, individual bar-code. Bar-code readers don't just help out at the checkout - they build up a stock list of items sold, so the store knows when to re-order new stuff.
Bar codes have a meaning because the meaning of a bar code is assigned to that bar code. A bar code identifies an item, and product information regarding that item is held in a data base.
The level of measurement of a bar code is nominal.
